Detachment of the amniotic egg. Preservation of pregnancy with detachment of the fetal egg

If a pregnant woman is diagnosed with such a diagnosis, then it should be remembered that this is not yet a sentence. With timely and proper treatment, everything can end well and a healthy child will be born.

Most often, detachment of the ovum occurs in the early stages of pregnancy and, unfortunately, it leads to spontaneous abortion. Sometimes a woman does not even have time to understand that her pregnancy has stopped, because she still did not suspect about her onset, attributing this to a failure of the menstrual cycle. But such a complication of pregnancy can occur at any time during the gestation of the baby. At a later date, this is called placental abruption.

The diagnosis itself sounds ominous. But a woman must understand what is actually happening in her body, and what is the reason for such a pathology.

After fertilization of the egg in the fallopian tube, the zygote, as the newly formed cell is now called, begins its movement to the uterus, where its further development will continue. This happens in about a week. At this time, the uterus is preparing to meet the "new tenant". Its walls become loose, the tone decreases, blood supply increases.

Once in the uterus, the fetal egg is attached to its walls, as if growing into it with the help of thin villi-capillaries, through which nutrients and oxygen will be supplied to it. Sometimes a fertilized egg cannot attach itself to the wall of the uterus. Often this happens due to the high tone of the uterus, as well as due to previous abortions or operations on the uterus. Without nutrition and oxygen, the embryo dies and is rejected from the body. Spontaneous miscarriage occurs.

But even if the zygote has already attached to the walls of the uterus, detachment of the fetal egg may begin. It can be partial, and occurs most often due to nervous strain, stress, heavy lifting, infections, or abdominal bruises.

In later pregnancy, the detachment of the ovum is called placental abruption. The cause may be late toxicosis, accompanied by an increase in blood pressure. With polyhydramnios or multiple pregnancy, intrauterine pressure increases. It can also lead to placental abruption.

Among the factors that can lead to detachment of the fetal egg, bad habits of a woman are also called - smoking and drinking alcohol. But this has not been reliably proven.

Signs of detachment of the ovum

The final diagnosis can only be made after an ultrasound examination. But if a woman has spotting from the vagina, pain, sharp or pulling, in the lower abdomen, general weakness and fatigue, then you should seek medical help. The woman should also be alerted by the fact that the child does not move for a long time, or his movements are weak. After an ultrasound, the doctor can say with certainty whether there is a threat to the life of the fetus, and whether it is possible to help a woman maintain a pregnancy. The placental abruption does not threaten the woman herself.

If the detachment of the fetal egg occurred by 1/3, then with the timely hospitalization of the expectant mother and the appropriate treatment, everything can return to normal.

Strict bed rest, elimination of any stress, both physical and emotional, is the key to success in the treatment of this pathology.

After a complete examination of the woman, complex treatment is prescribed. The most commonly used preparations containing progesterone. As a rule, after 10-15 days, the condition of the expectant mother stabilizes, and she safely carries the pregnancy to the end. But sometimes, especially in the later stages, you have to observe bed rest until the very birth.

If, after the examination, it turns out that placental abruption has occurred by half, then this is already a clear threat to the life of the fetus. The child does not receive sufficient nutrients and suffers greatly from asphyxia. In this case, premature birth is carried out by caesarean section.

The expectant mother should not be very worried and afraid that the detachment of the fetal egg will certainly occur. Precautions, of course, must be observed, but remember that such a pathology is rare, about one case in 120 pregnancies. And in almost 90% of cases everything goes well. Most importantly, avoid stress, strong fears, heavy lifting and abdominal bruises. Wise nature has taken good care of your baby to feel safe in his "water house".

Detachment of the ovum during pregnancy

As soon as she learns about her pregnancy, a woman must immediately begin to treat herself and her own health more carefully, carefully and responsibly. Firstly, from this moment on, the life of the unborn baby depends entirely on the well-being of the mother's body. Secondly, pregnancy itself causes a temporary decrease in a woman's immunity. Thirdly, none of us is immune from the development of complications when carrying a child. Fourthly, most of them manifest themselves precisely in the early stages of pregnancy - in the first trimester, which has the highest number of spontaneous abortions during pregnancy.

One of the most dangerous complications during the period of bearing a child can be detachment of the fetal egg during pregnancy.

Detachment of the ovum: symptoms

Detachment is said to be when the fetal egg prematurely begins to be rejected from the uterus, which, naturally, poses a threat to his life. Outside the uterus, the fetus cannot exist, and therefore complete detachment ends with its death and miscarriage. In fact, detachment is the initial stage of spontaneous abortion.

As the chorion peels off, the vessels that attach it to the uterus rupture, and a bruise occurs in this place - a hematoma. During the passage of an ultrasound, a specialist will certainly notice a hematoma forming near the placenta even at a very early stage. If the detachment is partial and not very pronounced, then perhaps this will be the only sign of a violation during pregnancy, fortunately detected during a routine ultrasound examination.

But very often a woman who begins rejection of the chorion or fetal egg is able to notice the symptoms of detachment on her own by changes in her own well-being and in the color of vaginal discharge.

The most characteristic sign of the onset of detachment and the threat of termination of pregnancy is spotting during pregnancy. Traces of brown gore indicate that the hematoma formed earlier, and this is the contents coming out of it. It is this kind of discharge that is characteristic of detachment of the fetal egg. The appearance of ichor from the genital tract indicates the "healing" of the tear, but relapses are not excluded. A change in spotting towards red is considered as a critical sign of a developing miscarriage and requires immediate hospitalization of the pregnant woman.

Threat harbingers can be cramping or pulling pains in the lower abdomen and in the lumbar region (reminiscent of menstruation), as well as a feeling of hardness of the uterus: due to increased tone, it spasms, rejecting the fetus, which a woman can feel as a petrification in the lower abdomen.

Detachment of the fetal egg: causes

Why the fetal egg of a normally started and seemingly successfully developing pregnancy suddenly begins to be rejected is not easy to answer. This can be facilitated by a huge number of various factors and reasons, among which experts distinguish the following:

  • hormonal disorders;
  • past abortive cleansing;
  • diseases of the reproductive system of the mother;
  • the presence of tumors of different etiologies;
  • inflammatory processes in the pelvic organs;
  • physiological pathologies in the development of gynecological organs;
  • infectious and viral diseases during pregnancy;
  • sexual infections in a pregnant woman;
  • high blood pressure;
  • the impact of harmful external factors on the body of the expectant mother (chemicals, gases, etc.);
  • bad habits during pregnancy;
  • strong physical activity;

Detachment of the fetal egg

Early pregnancy is most at risk. Most miscarriages occur in the first weeks of pregnancy. Therefore, newly-made expectant mothers should take care of themselves from the first days.

The cause of spontaneous abortion in early pregnancy may be the detachment of the fetal egg. Rather, it is its first stage. The fetal egg begins to be rejected from the chorion, a wound is formed here due to damage to the vessels, blood accumulates behind the fetal membrane, forming a hematoma, which is why this phenomenon in obstetrics is also called a retrochorial hematoma. This blood formation can increase and further contribute to the detachment of the fetal egg. Ultimately, there is its complete rejection and death.

If no action is taken, it is almost certain that the pregnancy will be terminated. However, timely treatment in most cases can stop the process.

Causes of detachment of the fetal egg

Why the fetus begins to be rejected in each case is almost impossible to find out. But there can be a large number of reasons contributing to such a beginning miscarriage:

  • hormonal disorders (in particular, a lack of progesterone in a woman's body);
  • pathology of the structure and development of the uterus;
  • gynecological diseases;
  • transferred infectious and viral diseases;
  • fetal malformations;
  • performing artificial abortions in the past;
  • other adverse factors (domestic, environmental, industrial).

Symptoms of detachment of the ovum

Unfortunately, it is not possible to predict detachment, but this can happen with any of the pregnant women. Therefore, each of them must be extremely attentive to themselves and immediately respond if any suspicious signs appear. The probable rejection of the fetus will first of all be indicated by pulling pains in the lower abdomen, which can radiate to the lower back as during menstruation, accompanied by spotting. You should immediately go to the hospital if you find traces of blood on the linen (with detachment, they have a coffee or bloody color). Brown discharge indicates that the hematoma is already beginning to resolve, but a second tear is not ruled out, therefore, if you do not want to tempt fate, then it is better to seek medical help. Usually a detachment is diagnosed by ultrasound.

By the way, there is an opinion that natural selection occurs at the initial stage of pregnancy. And if the fetus is complete and self-sufficient, then it will survive without outside help. In the process of his struggle for life, detachment can be repeated several times, but in the end, the fetal egg is securely fixed and begins to grow and develop safely.

In general, not all women prefer to go to the preservation of the detachment of the ovum in the early stages. However, doctors insist: the risks of abortion due to the onset of fetal rejection without treatment are incredibly high.

Treatment of detachment of the fetal egg

If suspicions of detachment of the fetal egg are confirmed, the woman will certainly be admitted to the hospital. Detachment is treated in a hospital and under the supervision of doctors, although you have the right to refuse hospitalization.

The most important thing when detachment has begun is the complete rest of the pregnant woman. You can not only do more or less hard work, but even walk. The abdominal wall should be in an absolutely relaxed state, and this is possible only in the prone position. When performing any actions, it is at least to the smallest degree, but still tenses, and when walking, vibration is still created and, in any case, intra-abdominal pressure increases, which also brings the uterus into tone and can only accelerate detachment. In addition, your doctor may recommend that you place a pillow or bolster under your buttocks to help drain blood from your pelvic area.

Too active intestinal motility now also poses a certain danger, which is why a woman is prescribed a sparing diet with the exclusion from the diet of foods that strengthen, weaken and cause gas formation, as well as coffee and tea.

There is no need to talk about sexual contacts: any sex with the threat of termination of pregnancy is strictly prohibited!

Equally important is the emotional peace of the expectant mother. It is necessary to exclude any stress and worries from a woman's life.

Unfortunately, medication is also not enough, but they help to keep the pregnancy, doctors say. These can be hemostatic drugs (Etamzilat), antispasmodics (No-shpa, Papaverine, Magne B6), sedatives (mainly Valerian Extract), vitamins (mainly folic acid and vitamin E), hormonal drugs (Dufaston, Utrozhestan) and others. All appointments must be made by the attending physician.

The duration of treatment in each individual case will be different, but it will be at least two weeks. In many ways, it depends on the degree to which a woman complies with all medical prescriptions. So if you want the fastest improvement, then follow them strictly.

In the future, a pregnant woman who had a detachment of the fetal egg in the early stages should be under strict medical supervision until the very end of gestation. Do not neglect scheduled check-ups and examinations. Gynecologists say that the increased risk of recurrence persists until the placenta completes its formation.

Detachment of the fetal egg

Symptoms, causes, consequences and treatment of detachment of the fetal egg

Detachment of the fetal egg is a fairly common pathology that occurs mainly at the end of the first and beginning of the second trimester of pregnancy. As a result of detachment from the chorion of the fetal egg, a hematoma is formed - a cavity with accumulation of blood. It is the hematoma that is diagnosed with the help of ultrasound, and on the basis of it a diagnosis of "threatened abortion" is made.

Symptoms of detachment of the ovum are always present in the case of a large detachment. These are bloody discharge from the genital tract and spasmodic pain. If the hematoma is very small, a few millimeters, it can only be diagnosed using ultrasound and is an accidental finding, while the woman considers herself absolutely healthy.

Many expectant mothers are interested in what causes the detachment of the fetal egg to occur in order to try to prevent the development of this pathology. However, there is no one specific reason. There are a lot of them. This is an increase in blood pressure, and, possibly, a lack of progesterone, and features of the chorion vessels, etc. Therefore, it is better not to study what a detachment of the fetal egg is without the need, but to register for pregnancy in a timely manner and undergo all recommended examinations on time, plus to this, observe the correct mode of work and rest, eat right.

The consequences of detachment of the fetal egg for the mother and fetus depend on its size. As a rule, with a detachment of more than 40 percent (compared to a fetal egg), a miscarriage occurs. With a slight detachment with a tendency to reduce the hematoma, there are no threats to the development of the fetus. This diagnosis may sound like this - partial detachment of the fetal egg with the formation of a hematoma. With such a diagnosis, a woman is placed in a hospital and the size of the hematoma is monitored by ultrasound. They must decrease. Brown discharge in the process of recovery is considered a positive diagnostic criterion - this is the “old” blood coming out, the hematoma is emptied. If, on the contrary, the hematoma becomes larger, the partial detachment of the fetal egg can become complete, and a miscarriage will occur.

As for the treatment, it is, for the most part, symptomatic. If there is uterine tone, it is removed with the help of tocolytic drugs. With abundant bleeding, hemostatic drugs are prescribed. It also makes sense to prescribe progesterone preparations, preferably Utrozhestan, in order to prevent a possible lack of progesterone and save the fetal egg with the embryo.

From the expectant mother herself, bed rest and cessation of sexual activity for at least a few weeks are required. Only such a detachment of the fetal egg in the early stages of pregnancy requires treatment, according to modern doctors. The main thing is to do everything so that nothing prevents the hematoma from emptying and reducing its size.

For example: fish

  • Inflammatory process in the pelvic organs;
  • Physiological disorders in the development of gynecological organs;
  • Infectious viral disease of the expectant mother during pregnancy;
  • sexual infection;
  • The impact of negative external factors on the body of a pregnant woman (gases, chemicals, etc.);
  • Too much physical activity;
  • Nervous shocks.

The main reason, according to the vast majority of experts in this field, is progesterone deficiency.

This violation prevents the further successful bearing of the child, since the body does not produce or produces less than necessary, the main hormone of pregnancy - progesterone. It is the latter that is responsible for the maintenance and development of pregnancy.

If a woman does not notice threatening signs or ignores them, no measures are taken, then in most cases the fetal egg will be completely rejected by the uterus. In this case, the pregnancy will either freeze, or a miscarriage will occur.

That is why the expectant mother should consult a doctor at the first disturbing symptoms, and if bleeding has already begun, then call an emergency and go to the nearest medical facility.

It should also be noted that with timely assistance to the hospital, there should no longer be any cause for alarm, because gynecologists and obstetricians currently have vast experience in the treatment of such pathological conditions. When applying, if it, of course, happened on time, the detachment that has begun can be eliminated as soon as possible.

In the case when there is a high probability that the partial detachment of the fetal egg will progress, the woman is placed in a hospital. In both the first and second cases, she needs absolute rest, which is not only in bed rest. You can not sit and walk, make sudden movements, sexual contacts are completely excluded, as well as stressful situations.

It is also helpful to lie down with your feet slightly above body level. In the first trimester, it is recommended to regularly measure the basal temperature, such a measure will allow you to monitor the course of pregnancy, for example, if the thermometer readings decrease, you should consult a doctor, as this is a bad sign.

To eliminate the tone of the uterus, antispasmodic drugs are prescribed, usually Papaverine, No-shpa or Magne B6. Relaxing and soothing therapy is also shown, which consists in taking valerian or motherwort.

If necessary, hemostatic medications (pr. Dicinon) and progesterone therapy (Dufaston, Utrozhestan) are prescribed. During the period of bearing a child, especially in the initial stages, it is recommended to take vitamins.

Often they are prescribed at the planning stage, but if a woman has not taken them, the gynecologist recommends folic acid, tocopherol (vitamin E) and multivitamins.

Vitamin therapy is standard during pregnancy, but the drugs may vary depending on the condition of the woman and the course of the process. Also, when detaching, it is recommended to adhere to a sparing diet, which refers to measures to prevent gas formation and stool retention.

After the threatening condition is eliminated, and the woman is discharged from the hospital home, it is necessary to monitor her pregnancy more carefully. Increased attention is provided, at least until the 16th week, however, both the woman herself and the doctors need to be on their guard until the birth itself.

It is quite possible to stop a dangerous violation and prevent a miscarriage. The main thing is that the first threatening symptoms are noticed in time. A woman should be extremely attentive, especially to the nature of the discharge, and must also adhere to the recommendations of doctors, because if you delay, the chance of maintaining a pregnancy decreases every minute.

It is necessary to regularly attend a antenatal clinic, take the required tests and undergo other studies, because this can be insurance against the development of various complications. Doctors can detect a disease or disorder at an early stage, and accordingly, take measures to eliminate it, which will save the expectant mother from problems during pregnancy.


The first few days from the moment of fertilization, the development of a fertilized egg is carried out at the expense of its own reserves. But they are not enough for a long time, and for a normal existence, the fetal egg must firmly attach to the wall of the uterus, where it will remain until the baby fully matures and is born.

Gradually, in the place where the fetal egg is adjacent to the endometrium, the placenta is formed. But until the moment of its complete formation, there is a risk of detachment of the fetal egg - that is, the connection between it and the uterine wall is broken.

Partial detachment is the appearance of a defect in the connection between the wall of the uterus and the fetal egg. This defect, due to a violation of the integrity of the vessels, is filled with blood, i.e. a hematoma is formed.

If the blood clotting is good, the blood vessels will clot, the hematoma will not increase, the detachment process will stop and the pregnancy will continue to develop.

If the body cannot cope with the bleeding, the growing hematoma will provoke further detachment, the connection of the fetal egg with the uterus will be completely broken, it will completely exfoliate and the pregnancy will be terminated.

How does detachment appear?

One of the main symptoms that may indicate a detachment that has occurred is pulling pain in the lower abdomen. The pain is somewhat similar to menstrual pain - the same obsessive-aching. Another sign is bloody discharge from the genital tract. If they are bright, then the detachment is fresh, and the bleeding has not stopped.

Brown discharge indicates that the vessels are thrombosed, the hematoma does not increase. However, both processes require an immediate consultation with a gynecologist and an ultrasound scan to assess the possible continuation of the pregnancy.

Currently, progesterones are widely used to maintain pregnancy in such conditions. However, not all experts are of the opinion that a pregnancy that wants to terminate should be maintained, they are sure that if the fetus is fully developed, then it will be able to survive on its own.

Of course, there is a rational link in this, but recently, more and more often, pregnancy is interrupted not because the fetus is not full-fledged, but because the mother's body cannot fully produce the substances necessary to preserve it.

The data obtained over many years of observation confirm that children born after the use of progesterones are completely viable and full-fledged.

Why exfoliate

In addition to the inferiority of the fetal egg, the cause of detachment can be gynecological diseases in an active form, hormonal disruptions, stress, tumor formation of the uterus, features of its structure (septum, bicornuate), infectious diseases, previous interventions - abortion, curettage, surgery.

The reasons directly dependent on the mother include the use of alcohol, drugs, excessive physical activity.

Detachment is a dangerous condition for the unborn baby at any time, because. leads to malnutrition, may lead to a violation of the laying of organs, their maturation.

One of the most reliable signs of pregnancy is a fetal egg. In the ultrasound picture, 2 weeks after the delay in menstruation, one can consider the formation, by the appearance of which one can determine the duration of pregnancy, the nature of its course and identify possible pathological processes of development. The normal shape of the ovum is round, the deformation of the ovum is a cause for serious concern, with this pathology additional examination and careful observation is required.

The structure of the fetal egg

In the first weeks of pregnancy, the fetal egg is a group of cells that, on the way to the uterus through the fallopian tube, continue their division in the form of an embryo and embryonic membranes. The outer layer of the egg is covered with chorion, the top layer that provides the embryo with nutrition and oxygen exchange.

The so-called "baby place", or placenta, is formed from the upper layer of the fetal egg, which is covered with villi. Destroying a small fragment of the uterine mucosa and vessel walls at the site of attachment, filling them with blood, the villi sink into the prepared place, where implantation takes place.

The structure of the fetal egg in the last trimester of pregnancy is the fetus, amniotic fluid, membranes, umbilical cord and placenta. The egg occupies the entire uterus and weighs about 5 kg.

Visualization of the embryo and ovum with ultrasound begins at a period of 6-7 weeks after the delay in menstruation. Already at this time, possible pathologies can be considered, such as: empty fetal egg, deformation of the fetal egg, detachment of the fetal egg, hematoma of the fetal egg, etc.

Due to the fact that the risk of spontaneous abortion, rejection and other pathologies is highest in the first trimester, ultrasound must be done in a timely manner, which will increase the chances of a successful correction of the situation.

The growth of the fetal egg

When conducting an ultrasound examination, an assessment is made of the internal diameter of the fetal egg - SVD of the fetal egg. To determine the gestational age, indicators of the coccyx-parietal size of the fetus (KTR) are used.

The growth of the fetal egg up to 15-16 weeks of pregnancy averages 1 mm per day, then from 2 to 2.5 mm per day.

For example, a fetal egg of 3 mm corresponds, as a rule, to three weeks of pregnancy, a fetal egg of 6.5 mm to five weeks.

When can I consider a fetal egg after IVF?

Many women who have undergone IVF (in vitro fertilization) (usually women who have had problems conceiving naturally for a long time) look forward with particular trepidation to the first ultrasound, which will help make sure that they have managed to get pregnant. Ultrasound, which is recommended for these patients to be done no earlier than 3 weeks after the procedure, will determine the presence, location and number of fetal eggs, which will confirm pregnancy.

Rejection of the ovum

The initial stage of spontaneous abortion due to any developmental anomalies is the rejection of the fetal egg. When the egg is detached from the chorion due to damage to the vessels, a wound surface is formed, an accumulation of blood occurs behind the membrane of the fetus, which is called "retrochorial hematoma of the fetal egg", an increase in which leads to miscarriage.

It must be understood that the hematoma of the fetal egg is not a threat of termination of pregnancy, but the result of detachment. If the embryo remains alive, the accumulation of blood does not harm the health of the woman and the fetus. A negative effect on the course of pregnancy is the continuation of detachment and an increase in the size of the hematoma.

Detachment of the fetal egg due to hematoma is not a hopeless process. With timely diagnosis, this process can be stopped, preventing the death of the embryo.

The causes of spontaneous abortion may be the following factors:

  • prolonged stress;
  • bad habits (smoking, drinking alcohol);
  • history of induced abortions;
  • viral, infectious diseases;
  • diseases of the organs of the reproductive system;
  • pathology of the uterus;
  • anomalies in the development of the fetus;
  • Rhesus conflict (mother and fetus), etc.

From the occurrence of such a pathology as the detachment of the ovum, unfortunately, not one of the pregnant women is insured. Treating yourself carefully, listening to your body, you can diagnose this pathological process in time, stopping its further progression.

Signs of detachment of the fetal egg (the first symptoms) may be pulling pains in the lower abdomen, accompanied by brown bloody discharge. Allocations of this type indicate the process of resorption of the hematoma, however, in order to avoid re-tearing, a woman should urgently contact a gynecologist who will establish the final diagnosis.

Repetition of detachment of the fetal egg can occur repeatedly, which does not pose a danger to a full-fledged fetus, which subsequently has a chance to securely attach and continue normal development. Without treatment, while being kept in a hospital, the likelihood of a miscarriage is very high.

The complete rest of the woman is one of the main methods of treatment. To ensure complete relaxation of the abdominal wall, the patient must strictly observe bed rest, getting up only when absolutely necessary. The most insignificant movements can increase intra-abdominal pressure, increase the tone of the uterus, which accelerates the process of rejection of the fetal egg. In order to ensure the outflow of blood from the pelvic area, being in a horizontal position, it is recommended to place a small pillow under the buttocks.

It is necessary to monitor the normal emptying of the intestines, preventing stool retention, which keeps the intestines in tension, the correct diet, the exclusion of foods that disrupt normal stools and cause flatulence.

It is very important to provide a calm psychological environment, without stress and emotional upheaval. Sexual life is also recommended to be limited for a while.

Along with these simple requirements, which a woman is able to fulfill on her own, there is a drug treatment prescribed strictly by a doctor.

If detachment of the ovum was diagnosed, hemostatic drugs (etamzilat), antispasmodic drugs (no-shpa, magne B6, papaverine), sedative drugs (valerian extract, novopassitis), hormonal drugs (utrogestan, duphaston) and vitamins (folic acid and vitamin E).

Even if a woman has her own prejudices towards drug treatment, she must correctly prioritize, realizing that it is impossible to maintain a pregnancy without drugs.

The course of treatment lasts, as a rule, two weeks, if necessary, it can be increased. The more demanding of herself a woman will be, responsibly fulfilling the doctor's prescriptions, the faster a positive outcome will come.

After completing the course of treatment, strict supervision of the attending physician is necessary until the end of pregnancy. It should be taken into account the fact that until the end of the process of complete formation of the placenta in a woman who has undergone a detachment of the fetal egg, the risk of re-rejection remains quite high.

The fetal egg is found on ultrasound in the form of a small bubble, usually at 4-6 weeks of pregnancy, and its size is considered the main characteristic. Normal development can slow down due to various pathologies. The most common is detachment accompanied by hematoma and possibly deformity.

normal development

It is at least incorrect to talk about the fact that the size of the fetal egg does not correspond to the gestational age. This parameter is very individual for each woman, in addition, a lot depends on the timing of ovulation. After all, the obstetric period is considered from the date of the last menstruation. And ovulation can occur in a week - then the fetus will be larger, or in three weeks, right before the expected period, and the fetus will be much smaller than the average value.

Although, of course, over decades of observation, some average parameters have been derived that doctors are guided by. For example, you can roughly say what gestational age corresponds to an embryo with a diameter of 3 mm - this is about four to five weeks. But only taking into account the fact that the woman ovulated exactly in the middle of the cycle, the calculations of physicians are based on this. Otherwise, it may well be two or three weeks, or even almost six.

little germ

Usually, such a small bubble may not be visible on the device, and this is quite normal. It is also difficult to determine how long if the dimensions are only 4 mm. It could be six weeks, or seven, or three, four, five weeks. And this size is not always possible to see on the screen during the first examination. It is prescribed if a woman goes to the gynecologist with a delay in menstruation.

To determine pregnancy, the results of the hCG test are taken into account. They may order urine and blood tests. The diagnosis is clarified by repeated ultrasound after 6-14 days. There are no real reasons for excitement yet, subject to normal health and the absence of any other symptoms.

A fetal egg with a diameter of 6 mm, and this does not indicate what the actual gestational age is, can be seen on almost any equipment. In general, the diameter of the embryo can be very different in women in the same week.

It is generally accepted that the discrepancy can reach one and a half weeks, both in the direction of decrease and increase. That is, when determining the gestational age of a woman with a fetal egg of 5 mm, we can talk about an approximate period of three to six weeks.

With this in mind, this table can be used as a guide. It shows the diameter of the embryo and the average number of weeks, you can add or subtract one week and three days to it. The internal diameter is taken into account, since it is it that is very clearly visible on ultrasound. The doctor writes down the average, since the fetus is not strictly spherical. This indicator is called SVD - the average internal diameter.

For example, with a fetal egg of 7 mm, you can roughly find out how long a woman has. This SVD corresponds to the value of 5 weeks in the table. We subtract a week and three days, add a week and three days, we get that the period is from three and a half to six and a half weeks. Of course, such a calculation is still approximate.

What is a detachment?

After fertilization, the egg travels through the fallopian tube to the uterus. All this time, it divides, first in two, then into four cells, and so on. This is the fertilized egg. By the time of implantation, its outer shell is transformed into a chorion with many villi-flagellums, with which the embryo penetrates the uterine wall.

Detachment of the fetal egg is the process when it separates from the already established chorion, which happens in the early stages of pregnancy. This is one of the most common diagnoses to treat a threat. Although we can say that in this way nature implements natural selection. After all, the causes of pathology are often associated with malformations, with diseases that make it impossible for the fetus to survive further.

But this situation can be observed several times. So just born life is fighting for its existence. Very often successfully, because many women do not even notice a mild degree of pathology and successfully give birth to a healthy baby. The fact that there was a detachment is revealed by ultrasound in the early stages or after childbirth, according to the scars that remain on the placenta.

What does it look like

The specific cause of the pathology is very difficult to determine. It can be called:

  • insufficient production of progesterone, which causes the uterus to tone;
  • neuropsychic shocks;
  • malformations of the uterus;
  • the presence of gynecological diseases;
  • tumors;
  • infections carried by a pregnant woman;
  • malformations of the embryo;
  • conflict of Rh factors in a pregnant woman and a fetus;
  • unsatisfactory environment (at home, ecology, at work);
  • alcoholism, smoking;
  • abortions in the past.

At what gestational age this will manifest itself, whether the diameter of the fetal egg is important, for example, 10 mm, is unknown. But the expectant mother is quite capable of influencing the development of the embryo. Based on the list, most of the reasons depend on it. Good nutrition, medical supervision, timely treatment of diseases, proper lifestyle can largely prevent serious consequences.

You need to take care of your emotional state. This is perhaps the most common cause of all the problems of modern pregnant women. Especially often they worry about incomprehensible wording. For example, having learned that “fetal egg 8 mm” is noted in the ultrasound transcript, they begin to find out what the gestational age is and whether it develops correctly in them.

Signs of a threatened miscarriage are feeling unwell and abdominal pain

Finding some far-fetched inconsistencies, they rush to "consult" on the Internet, with their girlfriends. Without understanding the situation, they worry, earning themselves serious problems. You can't do that. Not to mention everyday situations or working moments, which should generally fade into the background.

But if there is a real threat, then you need to strictly follow the recommendations of doctors. Its signs are:

  • red spotting;
  • stomach ache.

Allocations appear due to the fact that detachment in the early stages leads to the appearance of a fetal hematoma. This is due to the rupture of blood vessels. There may be no separations. The red ones are the most dangerous, this indicates that the process is under development.

Blood discharge becomes a serious reason for going to the hospital. They are accompanied by pulling pains in the abdomen. If the detachment was found on ultrasound, sent for treatment, after which brown discharge appeared, then this indicates its success. They are caused by the process of resorption of the hematoma, which can be confirmed by the doctor.

In addition to these symptoms, an uzist may indicate fetal deformity in early pregnancy. Usually it is caused by the tone of the uterus. When following the doctor's recommendations, you should not worry too much. But this symptom may indicate a missed pregnancy, the absence of an embryo, and other pathologies that require additional research.

Ways to treat pathology

Detachment treatment can be done at home or in a hospital. If its degree is mild or moderate, the doctor prescribes drugs that the woman should take at home. More severe cases require hospital treatment.

There is no dependence on the duration of pregnancy, the diameter of the fetus, which can be anything at the time of detection of the pathology, for example, 11 mm. But the threat of losing even such a small embryo can already be detected on ultrasound, which means that it is possible to save it. Of course, following the recommendations of the doctor.

It may be worth contacting a few more doctors, going to a paid clinic. If a pregnant woman does not trust her own doctor, it is worth seeing another. When the equipment is outdated, it is difficult to see the details. A woman who is not worried about anything may be healthy, and the diagnosis is made on the basis of distorted data.

Don't neglect your bad health

You can not do one thing - leave everything to chance. Even with a short gestation period, when the embryo is only 11 mm, there are very serious risks not only of losing the baby, but also of getting serious complications for your own body.

  1. Miscarriage.
  2. Necrotization of the endometrium due to filling with blood, followed by removal of the uterus.
  3. Severe bleeding with corresponding consequences, up to lethal.

Timely treatment is an almost guaranteed opportunity to avoid them.

Whatever the size of the fetal egg, at least up to 12 mm, at least more, at whatever stage of pregnancy the woman is, wherever she is treated - at home or in the hospital, the first requirement of the doctor will be complete rest. You just need to lie down, preferably with a raised pelvis. It is only allowed to go to the toilet or eat, but some even manage to do this while lying down.

A diet is prescribed that promotes normal intestinal motility. Too active contractions can lead to uterine tone. You can't have sex. You need to monitor your emotional state.

Medicines that help preserve the fetal egg during detachment are prescribed by a doctor. Usually these are drugs with magnesium, as well as hemostatic if necessary, relaxing smooth muscles, sedatives. Hormonal drugs may be used. Of course, special vitamin complexes are required.


Pregnancy is an unforgettable period in the life of every woman. Any future mother would like this time to pass without worries and worries. And what a pity if such an amazing time is overshadowed by the appearance of any problems. In the early stages of pregnancy, detachment of the ovum often occurs - a dangerous condition that threatens to terminate the pregnancy. What to do if such a nuisance happened?

Why does a fertilized egg exfoliate?

Under normal conditions, the fetal egg performs its protective function until the very birth. Its inner shell is called the amnion and faces the embryo. The outer shell (chorion) is attached to the wall of the uterus. In the second trimester of pregnancy, the placenta is formed from the chorion. In a normal situation, nothing prevents the fetal membranes from protecting the baby from external influences. Even periodic toning of the uterus should not lead to detachment of the fetal egg. Why does this situation happen from time to time?

Detachment of the fetal egg can lead to the death of the embryo and termination of pregnancy. There are several reasons that create such a situation in the early stages:

  • defect of the fetal egg;
  • chromosomal mutations of the embryo;
  • hormonal failure in a woman's body;
  • infectious diseases;
  • autoimmune processes;
  • diseases of the blood coagulation system.

There is an opinion that in the very early stages of pregnancy, detachment of the ovum is the result of natural selection. Thus, the body signals to the woman that the embryo is seriously ill and will not be able to exist safely after birth. Another thing is that modern medicine copes even with severe diseases of newborns. Many malformations are successfully treated immediately after the baby is born or even in the womb.

So what about a woman who has begun detachment of the membranes? Accept and wait for any outcome, or try to keep the pregnancy with all your might? None of the doctors can give an answer to this question. The decision remains with the woman and is determined only by her desire to maintain or terminate the pregnancy.

Options for detachment of the ovum in the first trimester

Departure of the membranes can occur in different ways. There are several situations in which spontaneous miscarriage occurs.

Biochemical pregnancy

This term is understood as a pregnancy that was interrupted for a period of 1-2 weeks, even before the delay in menstruation. At the same time, the fetal egg is not determined by ultrasound, and only a blood test for hCG makes it possible to find out that conception has occurred. Many women are not even aware that they were pregnant. For a period of about two weeks, detachment of the fetal egg occurs. Bloody discharge from the genital tract appears, which is taken by a woman for menstruation. The cause of a miscarriage at this time is considered to be a defect in the fetal egg, which occurred even at the time of the formation of the embryo. Hormonal imbalances are not excluded.

Incomplete detachment of the fetal egg (beginning miscarriage)

In this situation, only part of the fetal membranes exfoliate from the uterine wall. A hematoma is formed - a blood clot between the chorion and the uterus. A woman has pain in the lower abdomen and bleeding from the genital tract of varying degrees of intensity. Incomplete detachment does not always end in miscarriage. If the heart of the embryo beats, there are considerable chances to keep the pregnancy.

Complete detachment of the ovum

In this case, the fetal membranes exfoliate from the walls of the uterus and the embryo dies. The uterus comes into tone, trying to get rid of the fetus. There is a strong cramping pain in the lower abdomen, radiating to the lower back and sacrum. Bleeding develops, often threatening the woman's life. It is impossible to save the pregnancy in this case.

Non-developing pregnancy

The condition in which the death of the embryo occurs before the detachment of the fetal egg is called a non-developing (regressive) pregnancy. In this case, the heartbeat of the embryo on ultrasound is not determined. The uterus decreases in size, all signs of pregnancy disappear. There are bleeding, pain in the lower abdomen. Detachment of the fetal egg does not occur immediately, but only a few weeks after the death of the embryo. In many cases, the membranes never come out on their own and have to be surgically removed.

Diagnosis of detachment of the fetal egg in early pregnancy

If a detachment of the membranes is suspected, a gynecological examination and ultrasound examination are mandatory. On ultrasound, the doctor assesses the condition of the chorion (the outer part of the fetal egg), notes whether there is a hematoma. Be sure to listen to the fetal heartbeat. An ultrasound examination can detect a fetal egg for a period of 3-4 weeks, and listen to the baby's heart after 6 weeks.

Methods of treatment of detachment of the fetal egg in the first trimester

In early pregnancy, therapy is carried out only if the embryo is alive, and its heartbeat is heard on ultrasound. To eliminate hormonal disorders, progesterone preparations are prescribed. These funds create the optimal hormonal background for the development of pregnancy up to 14-16 weeks. After 16 weeks, progesterone begins to be produced by the placenta, and the need for its intake from the outside disappears.

To relieve pain and reduce the tone of the uterus are used antispasmodic drugs. In the first trimester of pregnancy, drotaverine or papaverine is used. Both of these drugs effectively eliminate uterine hypertonicity and reduce the risk of spontaneous miscarriage.

To maintain general immunity and increase the body's defenses, a pregnant woman is recommended to take vitamin complexes. If, against the background of toxicosis, multivitamins are not absorbed, you should drink at least folic acid. Of great importance is good nutrition, as well as a properly organized daily routine. For the entire period of treatment, physical activity and sexual activity are prohibited.

Prevention of detachment of the fetal egg has not been developed. Refusal of bad habits and timely treatment of infectious diseases of the uterus and appendages reduce the risk of spontaneous miscarriage. Before planning a pregnancy, it makes sense to undergo a full examination by a specialist in order to exclude the possibility of hormonal disorders and other health problems.
