Dangerous periods after IVF

If your position is positive result in vitro fertilization (IVF), then you probably already know that with this method of conception, the possibility of having not one, but two children is very high. Hence the risk, because it is difficult to carry and give birth to one baby, and if you have two of them, then the responsibility and complexity of the periods only increase.

In addition, it is important to know the following difficulties that arise after IVF:

  • increased risk of early miscarriage: most often, to minimize such cases, gynecologists prescribe to pregnant girls hormonal preparations;
  • the causes of infertility of the expectant mother can also affect the very course of pregnancy, the appearance of genetic abnormalities in the child.

All this can be prevented by close attention to your health, condition, as well as an immediate trip to the doctor or his call in case of the slightest ailment.

The very first weeks of pregnancy after IVF are the most dangerous. The fetus needs to gain a foothold in the woman’s egg, “grow” with the placenta, but everything is aggravated by the very process of maintaining pregnancy: taking hormones, in a non-standard way conception (population of eggs), which can also help reduce corpus luteum such cells. And also the woman's body itself, more precisely the immune system, can reject the baby, forming antibodies. Similar conditions accompanied by detachment of the placenta, contribute to the appearance of bleeding and miscarriages.

A well-deserved joy is being a mom

That is why all the actions of doctors aimed at preserving the fetus begin from the very first week of conception and are carried out with more powerful estrogen and progestin drugs.

Rules of conduct at critical moments

As you can see for yourself, dangerous weeks during pregnancy exist in each of the trimesters, and the fact remains that there is no definite answer which week of pregnancy is the most dangerous, because with all the adverse outcomes, the life of your unborn child will be in jeopardy. The goal of every girl who already at the first signs of pregnancy feels maternal instinct, this is the birth of healthy and strong offspring, so it is very important to take care not only of your health, but also emotional state.

Pregnancy is an unforgettable time in every woman's life. The message about the onset of pregnancy is, of course, happy news. But at the same time, every woman understands that now she is standing in her own everyday life make adjustments. After all, now she is responsible not only for her health, but also for the health of the unborn baby. In the modern rhythm of life, there are many factors potentially dangerous for a pregnant woman: poor ecology, unhealthy diet, forced physical activity. Chronic diseases and even stress can provoke a miscarriage. In each trimester, doctors identify critical periods when every expectant mother should be especially attentive to health. Let's consider each of them.

Dangerous weeks of the first trimester

There is an opinion that the first three months of pregnancy are the most dangerous, since the risk of miscarriage is three times higher in the first trimester. During this period, organs are formed in the unborn baby. Of course, such important process and for a woman can not pass unnoticed. It is marked by nausea, lethargy, fatigue and frequent urination in a pregnant woman. There are three critical periods.

The first - from 14 to 21 days of pregnancy, when future mommy may not be aware that he is in an "interesting" position. At this time, the fertilized egg is introduced into the mucous membrane of the uterine wall.

This period may vary if one of the following factors exists:

  • In the structure of the uterus there are anomalies or scars after operations (after caesarean section);
  • The embryo has genetic and chromosomal abnormalities;
  • A pregnant woman is stressed;
  • infectious and viral diseases at mother;
  • Smoking and drinking alcohol.

Under the influence of these factors, spontaneous miscarriage can occur, which will be manifested by bleeding similar to menstruation.

In the period from 4 to 6 weeks, the laying of the vital organs of the embryo takes place. Many factors can affect the formation of the organs of the fetus, so some doctors also define this period as critical.

From the 8th to the 12th week of pregnancy, growth and development occurs. children's place", placenta. In some women, a hormonal surge occurs in the body, which can lead to wrong development placenta and, as a result (in 75% of cases), to miscarriage or miscarriage.

At this time, you should not take antibiotics, hormonal drugs, antidepressants. It is also undesirable to take some herbs, such as comfrey, hay, juniper, coltsfoot, etc. It is recommended to pay attention intestinal microflora and sleep. It is not recommended to be under the scorching rays of the sun.

According to statistics, 25% of all fertilized eggs live for about 4 weeks and die without infiltrating the uterine mucosa. At this time, women may not even suspect that conception has occurred.

Second trimester: what to watch out for

The second semester is the period from 13 to 24 weeks of pregnancy. It " golden mean”, when toxicosis, nausea and headaches recede, physical education for pregnant women is shown, walks on fresh air.

Hormonal changes in the body continue, often characterized by vaginal discharge. The risk of infections increases. Therefore, any changes in secretions require vigilant attention in this trimester: density, color, smell, burning.

Colds female body exposed throughout pregnancy, however, at 15–16 weeks, a cold can affect the formation of the bone tissue of the embryo, and at 19–20 weeks of pregnancy, the formation of eggs in the future girl.

The pregnancy calendar is known to every expectant mother, but which weeks you need to pay attention to Special attention not everyone knows

However, the critical period in the second trimester of pregnancy is 18-22 weeks. At this time, the uterus is actively growing, manifested by such unpleasant phenomena like heartburn, constipation and back pain. There is a risk of premature termination of pregnancy for the following reasons:

  • infectious disease of the expectant mother;
  • weakening of the cervix;
  • misplaced placenta.

Summing up, in the second trimester, it is imperative to pay special attention to secretions and it is necessary to treat infections under the supervision of a doctor.

Dangers of the third trimester

During the third trimester of pregnancy, most women experience fatigue, there is shortness of breath, they do not sleep well. The main dangers that await a woman during this period of pregnancy are associated with premature birth. Critical in the third trimester include the period from 28 to 32 weeks of pregnancy. At this time, the risk of premature birth increases significantly for the following reasons:

  • hormonal disruptions;
  • early aging and placental abruption;
  • late preeclampsia;
  • insufficiency of the placenta.

Characteristic signs that pregnancy is under threat will be aching and growing pain in the lower abdomen, fever, and bleeding.

So, as we have already decided, in each trimester of pregnancy there are “critical” weeks. In the first, it is the likelihood of developing malformations in the fetus and the threat of miscarriage. In the second - the risk of developing vaginal infections and premature birth. In the third - birth premature baby. In order to avoid the occurrence complications for their health, and for the health of the baby, you need to register as early as possible in antenatal clinic and follow the instructions of the doctors. Be attentive to yourself, because not only your health, but also the health of your unborn child depends on you!

A desired pregnancy is one of the happiest periods in a woman's life. But, unfortunately, a variety of factors environment lead to problems and complications natural process bearing a baby. Women are especially sensitive to negative influences on the certain deadlines. It is about what are the most dangerous periods of pregnancy, how to endure them without complications, that will be discussed in our article.

What are the dangers of the first weeks?

Despite the fact that in the first period of pregnancy a woman does not feel pronounced changes in the body, in fact, it is at this moment that significant for further changes occur. normal development baby processes. In the first, the embryo attaches to the wall of the uterus, as well as the laying of the internal organs of the baby. But the placenta has not yet formed during this period, so it cannot perform protective function protecting the embryo from external negative factors.

In addition, often a woman may still not be aware of her condition, continuing habitual image life. The expectant mother, not knowing about the pregnancy, may take medication, be exposed to excessive physical activity, stress. All these factors can lead to a violation of the development of the embryo, and, as a result, to a complication or spontaneous interruption pregnancy.

Critical stages of the first trimester

In medicine, such critical periods of pregnancy are distinguished:

  1. The stage of attachment of the fetal egg to the wall of the uterus (second week of pregnancy). Complications can occur both as a result of a woman’s diseases (for example, with uterine myoma), and under the influence of external factors(reception medicines lifting weights). If for some reason the fetal egg has not attached to the uterus, then the woman may never know that conception has occurred in her body, since the uterus will be cleansed during the next menstrual flow. An unfavorable prognosis for the subsequent development of pregnancy exists in the case of pathological attachment germ. In such a situation, a woman needs stationary observation.
  2. The second week of pregnancy from conception (or the fourth obstetric) carries the danger of fading the development of the child. Often the causes are serious, often genetic pathologies of the embryo.
  3. At the stage of placenta formation (8-12 weeks), it is extremely an important factor is the hormonal health of the expectant mother. Any deviations can lead to pathological development of the protective barrier and impossibility further development embryo. When the placenta is dysfunctional, doctors often fail to maintain the pregnancy. Miscarriages may occur spontaneously, or medical attention may be required in case of fetal development.

Causes of pregnancy complications in the first trimester

Summarizing all of the above, we can identify the most common causes of violations in the development of pregnancy on early dates:

  • unfavorable state of health of the expectant mother (including " female diseases», hormonal disorders);
  • congenital or acquired structural anomalies reproductive organs(for example, scars, disorders in the formation of the endometrium, and others);
  • reception medicines, alcohol;
  • physical stress;
  • stress;
  • genetic malformations of the embryo.

All factors that may adversely affect intrauterine development baby, it is impossible to predict and eliminate in time. However, concern for own health and regular visits to doctors to preventive examination significantly reduce the risks possible complications in case of conception.

Today, almost every perinatal center There is a family planning department. Here, future parents can get professional advice, go through the necessary medical examination and, if necessary, treatment.

  • refusal of drugs that may adversely affect the development of the embryo;
  • reduction of physical and emotional stress;
  • proper nutrition;
  • hiking in the fresh air;
  • reducing the time spent at the computer and other electronic gadgets;
  • complete rest;
  • moderation in sexual relations, and if necessary, complete rest;
  • refusal to travel long distances.

If the woman is at risk, the doctor may recommend that the expectant mother stay in the hospital. Thus, the most dangerous periods of a woman's pregnancy are under the supervision of specialists, which significantly reduces the likelihood of possible complications.

When do you need to urgently call a doctor?

You should contact your doctor immediately if you are concerned drawing pains at early pregnancy in the lower abdomen, as well as smearing brown or scarlet discharge from the genital tract. These symptoms may be harbingers spontaneous miscarriage.

Dangerous stages of the second trimester

The middle of pregnancy for most women is a stage of calm and full enjoyment of the situation. But even during this period there are so-called critical weeks. What are the most dangerous periods of pregnancy in the second trimester? It is noted that various deviations are more often observed from 18 to 22 weeks. Causes of complications in this stage any infectious disease suffered by the expectant mother can serve. In addition, improper attachment of the placenta can also cause many problems. But with the timely detection of pathology using an ultrasound examination, the doctor may recommend hospitalization for the woman.

Another frequent in the second trimester is a condition such as isthmic-cervical insufficiency of the cervix. This pathology is also diagnosed by instrumental methods and solved with the help of surgical intervention.

Maintaining the health of the expectant mother and her baby will help regular examinations. A pregnant woman is recommended to take tests in a timely manner, to comply with all doctor's prescriptions. To reduce the risk of contracting infectious diseases, visits to crowded places should be limited. a large number people, do not forget about walks in the fresh air.

Critical stage of the last period of pregnancy

The third trimester is dangerous for premature birth. A baby is considered premature if born between 28 and 32 weeks of gestation. The baby may be born unviable or with serious pathologies. What can cause a baby to be born prematurely? The most common factors that can lead to this complication of pregnancy are the following:

  • physical impact (strike);
  • symptoms of late toxicosis (gestosis);
  • violation of the functioning of the placenta (abruption, functional failure);
  • violation of the amount of amniotic fluid;
  • which can take place on different reasons.

Risk group

AT obstetric practice there is such a thing as pregnant women at risk. These patients include expectant mothers who have chronic diseases, have a history of miscarriage or the birth of a child with malformations. In addition, if during a blood test it is found in a woman during pregnancy, then the expectant mother is also classified as a risk group due to high probability development of Rhesus conflict between mother and fetus.

How to maintain the health of the expectant mother and her baby during the most dangerous periods of pregnancy? It is enough to visit an obstetrician-gynecologist in a timely manner and undergo all recommended diagnostic tests. Following the instructions of a specialist significantly increases the chances that pregnancy will pass without complications, and the baby will be born healthy.

Without exception, all expectant mothers should know that directly during pregnancy there are really strictly defined time periods during which the risks of terminating the current pregnancy may increase. These are the ones who modern medicine It is customary to call the most dangerous weeks, since they can significantly increase the risk of miscarriage for those pregnant women who are initially in any of the risk groups. And that is why an urgent, and therefore timely appeal to the attending physician for pregnancy management is really extremely important to carry out precisely at the earliest stage of pregnancy. Next, we will take a closer look at those most incredibly dangerous periods and all the signs characteristic of them, when an interruption of the current pregnancy can actually occur.

First trimester of pregnancy

One of the first dangerous periods is considered to be the period that occurs approximately from 14 to 21 days of pregnancy. Moreover, very many women during this period of time may not even be aware of the onset of their “interesting position”, since in the first weeks, usually, only attachment to the walls of the mucous membrane of the uterus of the fetal egg occurs. In the event that a woman initially had some inflammatory process endometrium, or there may be other pathological changes in the uterus - the introduction of the fetal egg simply does not occur. Besides, the real reason Such an early miscarriage may well be served by such existing diseases as: ordinary or major postoperative scars directly on the walls of the uterus. As well as all chromosomal or genetic abnormalities in the development of the embryo itself, they are also able to actively prevent the introduction of the fetal egg into the walls of the uterus.

The second of the most dangerous periods of the first trimester is the period from 8 to 12 weeks of pregnancy. It is during this period that growth and further usually occur, but the main reason for the occurrence of miscarriages at this time is sharp hormonal disorders that simply prevent it normal growth and development accordingly.

Second trimester of pregnancy

Further, in the second trimester of the current pregnancy, the most dangerous of all periods is considered to be the period from 18 to 22 weeks of the current pregnancy, because it is at this time that a rather active and most important fast growth uterus in size.

During this period, the risk of developing such dangerous conditions as:

  • wrong location the placenta itself.
  • Risks of emergence of new infectious diseases.
  • A sharply weakened position of the cervix itself.

And, of course, all of these diseases may well lead to spontaneous miscarriage. And that is why, a timely appeal to doctors for the purpose of diagnosing at the slightest ailment in a pregnant woman is truly extremely important, and it is during this dangerous period of pregnancy.

Third trimester of pregnancy

Usually, it is in the third trimester of the current pregnancy that the most dangerous of all weeks are the days between 28 and 32 weeks of pregnancy. The main, and sometimes death in this case, the fetus are such most dangerous conditions how:

At the same time, it is extremely important to take into account that children born precisely during this period are usually considered premature and will require especially scrupulous and careful care from doctors and parents in the future.

Based on the foregoing, we will make a simple conclusion that timely registration of pregnancy and at the same time strict adherence to all key recommendations doctors will definitely be able to help you avoid all these extremely dangerous periods of pregnancy and become the happiest mother of the healthiest and strongest baby in the future!

It is no secret for every pregnant woman that there are dangerous periods when carrying a child right up to the very birth. They are usually divided into certain weeks and have their own factors.

What are the most dangerous weeks of pregnancy? A woman's monthly cycle is approximately 25-28 days. And when she became pregnant, and this cycle has not yet had time to “slow down”, this can be a serious threat to pregnancy. Doctors determine the first trimester, namely: the fourth, eighth and twelfth weeks of pregnancy. These terms are dangerous in that there may be a loss of the fetus, which has not yet taken root so firmly in the mother's womb. Especially at 8 and 12 weeks, when the baby is already laid internal organs and the baby begins its development, and the woman's body is perhaps not ready or not mature for a number of reasons and factors. At these pores, the abdomen is not visible at all, the baby is the size of a pear or an apple, and if you feel that your lower abdomen is pulling or you notice bloody issues, consult a doctor, it may be a threat of miscarriage.

Dangerous weeks of pregnancy in the second trimester


Usually, after the twelfth week, everything calms down and proceeds normally and without failures, however, already at about the 16th or 17th week, troubles can occur. A woman may experience isthmic-cervical insufficiency, which is popularly called "weakness of the cervix." This diagnosis means that the cervix is ​​weakened or dilated and cannot hold the fetus, which can lead to premature breakage of the water and childbirth. And if this happened before 24 weeks, it is almost impossible to save the child. In this case, the uterus is "sutured", and then the woman bears the baby either up to 34 weeks or even up to 38-39.

This diagnosis may be due to various factors: too frequent sexual intercourse during pregnancy, alcohol, cystitis, congenital pathologies at mother.

Dangerous weeks of pregnancy in the third trimester

This trimester is considered full-term, even if preterm labor occurs. But there are problems that you can face and lose the fetus. In the third trimester, the most dangerous weeks are 29, 32 and 34. At this time, the baby may "starve" due to depletion of the placenta for various reasons, for example
the mother is infected (influenza, SARS, sexually transmitted diseases, foodborne infections, etc.). Also at this time, it is sometimes observed late toxicosis(preeclampsia), which often leads to uterine hypertonicity, premature waters and may also threaten the life of the mother herself.

Things to remember

  • Firstly, if a woman, being pregnant in the early stages, drinks alcohol, smokes, takes narcotic drugs (pills, marijuana, hard drugs), pathologies in a child are unlikely to be avoided, especially at week 12, it is then that all vital organs are laid, and this process is the most important. If a woman does not know about her pregnancy, and did not plan it, you should consult a doctor and get tested, and of course stop harming your own health and the health of your child.
  • Do not forget that preeclampsia can occur due to malnutrition or also alcohol or cigarettes. Do not overeat, give up even a glass of cognac or a smoked cigarette, sleep normally, be outdoors more often, drink more pure water, eat less fried and smoked, more fiber (vegetables, fruits, boiled meat, fish).
  • It should be remembered that it affects the severity of the health of the pregnant woman and the adoption of antibiotics of any group. Having heavy enough chemical composition, which is aimed at destroying any infection, antibiotics affect the entire body, especially the stomach and liver. Therefore, if you catch a cold, you should not drink something at your discretion, consult a doctor. But if you have urinary infection(cystitis, STDs) then you will be prescribed drugs, but strictly under the supervision of a doctor.
Also, do not forget that if a woman already had problems with her first pregnancy (miscarriage, preeclampsia leading to premature birth, fetal fading, etc.), she should respond to everything that might disturb her and immediately consult a doctor.
