During pregnancy, the test may show a negative result. Why does a pregnancy test show a negative result?

Many women dream of pregnancy so much that they listen to the slightest changes in their body. A delay in menstruation for at least one day already encourages them to run to the pharmacy for a miracle test that allows you to determine pregnancy at home at an early stage. And what a disappointment when, instead of the cherished two strips, the test shows a negative result. It turns out that one strip cannot guarantee a 100% absence of pregnancy. That is why, in addition to the test, it is necessary to pay attention to other symptoms and indicators that indicate that pregnancy is possible.

How does a pregnancy test work?

Even in ancient times, women noticed that a delay in menstruation can be directly related to pregnancy. In 1350 B.C. came up with a way to confirm or deny the onset of pregnancy. Women urinated on wheat and barley seeds and evaluated the results after a while. If the seeds did not germinate, then pregnancy did not occur. If the seeds sprouted, then one could talk not only about the onset of pregnancy, but also about the field of the future baby (sprouted wheat promised a girl, and barley promised a boy).

In 1963, scientists, after conducting their research, found that such a diagnosis works, and the seeds really germinate faster due to the increased level of estrogen in the urine of a pregnant woman. At the same time, the development of modern tests began.

The first test strips, which allow you to get results relatively quickly, appeared in 1988. Over time, they improved and today they allow to determine the onset of pregnancy with high accuracy within 5 - 10 seconds.

The principle of operation of pregnancy tests is simple. The test reacts to the hCG hormone, which begins to be actively produced in the woman's body from the first hours after fertilization.

On the 12th - 15th day after fertilization, the concentration of this hormone in the urine reaches the level at which the test system is able to determine it.

Just by this time, the woman is already experiencing a delay in menstruation. To carry out the test, it is necessary to make contact of the test strip with urine, collecting it in a separate container or urinating directly on the test system and after a certain time evaluate the result. The instructions say that two strips mean a positive result, and one strip indicates the absence of pregnancy.

Causes of a false negative pregnancy test

The accuracy of readings obtained after using a pregnancy test ranges from 75 - 97%. Thus, the manufacturer himself admits the possibility of both a false positive and a false negative result.

There are various reasons why a woman may get a negative pregnancy test:


The main symptoms of pregnancy

The main symptom that women and doctors mostly associate with the onset of pregnancy is the delay in menstruation. But there are others that may appear even before the expected date of menstruation.


Pregnancy diagnostics

If a woman has a delay in menstruation, other symptoms appear that indicate a possible pregnancy, but despite this, the test stubbornly shows a negative result, then you need to see a doctor and find out why such changes have occurred.

Medicine owns more accurate methods of early diagnosis of pregnancy, which include:

  • Blood test for hCG. The fact is that the concentration of chorionic gonadotropin in the blood is much higher than in the urine. In addition, this hormone can be determined in the blood even before the delay, starting from the first day after fertilization. Therefore, it happens that the concentration of hCG in the urine is not enough for a pregnancy test to determine it, while a blood test shows a positive result.
  • Ultrasound examination of the uterus. According to the results of an ultrasound scan performed by a transvaginal sensor, it is possible not only to determine the presence of pregnancy, but also to establish its duration and features of development.

A negative pregnancy test is not always a reason to completely exclude it. Women who are not pregnant for the first time may suspect their position much earlier than even the most accurate test determines it. Therefore, you need to take care of your health. Not only the delay in menstruation, but also other visible symptoms, should be suspicious. If you have any doubts, you should consult a doctor, since a false negative pregnancy test can be a signal indicating any violations in the woman's health or the development of pregnancy.

Hands are shaking, there is fog in my head, an incomprehensible mixture of emotions inside, and the reason for everything is a positive pregnancy test. Some women rejoice at him like a miracle, others begin to panic, others completely fall into a stupor. But after a few minutes / hours / days, everyone has the same question - what's next?

1. Calm down

It is better not to neglect this advice. Very often, women who really want or, conversely, are afraid to get pregnant “think out” the second strip. In any case, pulling yourself together will be a great solution.

You can not try to be distracted by something else - it will not work. Instead, taking deep, calm breaths or talking to your spouse/girlfriend will help.

2. Recheck the result

As soon as the ability to think clearly returns, it is advisable to start rechecking the result. To do this, it is better to buy 2-3 tests, but of a different brand and type. Ideally - in another pharmacy. Reading their instructions is a must. Tests may show false positive results due to misuse, storage or expired use.

A false positive result also occurs in such cases:

  • recent abortion, miscarriage;
  • ectopic pregnancy;
  • getting on the test of organic particles from the outside;
  • treatment with hormonal drugs;
  • menopause;
  • oncology;
  • some types of cysts, uterine fibroids and similar diseases.

You can repeat the procedure after 2-3 days, if in doubt. In the presence of pregnancy, the stripes will become brighter after this period. If the tests still show pregnancy, it's time to move on to the third step.

3. Chat with mom

And not only for moral support and sharing of joy. A conversation with her mother is needed to find out how her pregnancy and childbirth went. This information will later help the doctor to better understand how to manage the pregnancy of the expectant mother. A few questions to ask your parent:

  • What weight and height was I born with?
  • Were there complications during pregnancy or childbirth?
  • Did you suffer from high blood pressure during pregnancy?
  • What childhood diseases did I have (rubella, chickenpox, etc.)?

It also makes sense to remember all your chronic or serious diseases in the past, the presence of allergies. Maybe mom can help with that too.

4. Make an appointment with a doctor

A natural and obvious step. However, as practice shows, many women postpone a visit to the doctor or do not consider it necessary to go to the clinic at all. And in vain. The sooner the expectant mother makes an appointment, the more chances the doctor has to prevent the development of pathologies in the fetus or complications during pregnancy.

If the test showed two strips not due to pregnancy or product defects, the doctor will determine the cause and prescribe the appropriate treatment.

What can the doctor do during the first visits?

4.1. Submit for hCG lab test

If the period is still short, even a gynecological examination may not reveal pregnancy. But the test for gonadotropin will do just fine with this. It is much more in the blood than in the urine. If the pharmacy test showed an incorrect result, the laboratory will reveal this.

4.2. Run diagnostics

The doctor may order several blood tests, urine tests, and a thyroid examination. He will certainly recommend a general examination by a general practitioner, an ophthalmologist, an otolaryngologist, and several other specialists.

You will often have to take tests during pregnancy, almost before every visit to the gynecologist. However, it is best not to skip them as they are really important for maintaining a healthy pregnancy. All procedures are aimed not only at monitoring the child's condition, but also at taking care of the mother's well-being.

Low hemoglobin levels, weak immunity, too strong hormonal surges and discomfort in general - for all this, a gynecologist can prescribe vitamins. They will improve a woman's health and even make her more attractive.

4.4. Assign an ultrasound

The first ultrasound will be scheduled no earlier than 2 weeks after the start of the delay. Its main goal is to rule out an ectopic pregnancy. It will also be able to identify problems with the genitals, if any.

Ultrasound to determine the sex of the child, the features of its development will be prescribed much later.

4.5. Coordinate visit schedule

You will have to see the doctor almost more often than your husband. If the pregnancy passes without complications, then the frequency of visits will most likely be equal to one trip per month, but not less often. Closer to the due date, a woman will have to visit the gynecologist even more often.

So that later you do not have to cancel plans and rush to get to the doctor, it is advisable to immediately discuss with the doctor the approximate schedule of visits.

5. Stock up on information

Books, reliable online sources, courses for pregnant women - all this is sure to come in handy. A woman who knows how her body and the child changes during gestation feels more confident. And confidence and calm make childbirth easier.

What is definitely better not to do is listen to adherents of traditional medicine with dubious, and often dangerous advice. These 9 months are not the best period for experiments.

6. Enjoy your pregnancy

Almost every pregnancy is accompanied by discomfort. This is natural and quite tolerable. However, it is better to try to provide yourself with the most comfortable environment.

Communication with nice people, visiting beautiful places, positive emotions have a good effect on the nervous system of the baby and his health in general. Yes, and mom from this only benefits.

And yet there is a “but”. Pregnancy is not the best time for drastic changes. Therefore, if a young mother:

  • smokes she can't give up this habit sharp. Better gradually reduce the number of cigarettes, and then smoothly refuse them;
  • living on a broken schedule she will have to try slowly restore it. It makes sense to ask the future dad about it;
    • , it is recommended to exclude strength and intensive training. You can replace them with simple walks or yoga for pregnant women;
  • loves fast food, it is desirable to reduce its quantity. A woman's tastes can change dramatically, which often provokes cravings for junk food. You should not completely deny yourself pleasure, but seriously limiting the amount of such food is a necessity. At the same time, it is important to ensure that the main diet consists of predominantly from healthy meals.
  • active personality who does not sit still, she can leave her former way of life. But she will definitely have to monitor her daily schedule and nutrition, eliminate negativity and overwork.

A positive pregnancy test can be both the result of a defective product and an omen of motherhood. Regardless of this, it is better to play it safe and still visit the doctor's office. Such a step will help protect the health - yours and the baby.

It happens that a woman has a delay. The first thing that comes to mind is to do a test. The strip shows a negative result, but the monthly did not come. And signs of pregnancy begin to appear: slight nausea, dizziness, and now the doctor confirms the presence of a fetal egg, but it turns out that there is a pregnancy, but the test is negative. What does it depend on?

You should not be afraid. Most likely, you made a mistake in the calculations of the cycle. Usually it is 26-30 days, but not everyone is regular. Therefore, the dates of ovulation and implantation can be erroneous. If the amount of hCG is too low, then the result will be negative. Pregnancy hormone levels are rising every day. It is almost impossible to calculate everything with accuracy. In this case, it is necessary to repeat the diagnosis in a week.

If there is a pregnancy and the test is negative, a test strip error may be the cause. The reasons most often are violation of storage rules, marriage, expired, improper use. It is better to buy 2 tests from different manufacturers at once.

There is a mistake even due to the intake of diuretics. There is a "dilution of the composition of the urine." This, in turn, reduces the amount of hCG, and it turns out that there is a pregnancy, but the test is negative.

Rules for conducting home diagnostics

A small digression. To avoid unnecessary worries, you need to know correctly:

Diagnostics should be carried out only in the morning;

Collect urine only in a clean and dry container;

10-12 hours before the test, limit fluid intake;

Stop taking medications.

It rarely happens that pregnancy is at risk. half is alien to the woman's body, and he rejects it. The reasons are actually different, only the gynecologist will determine the exact one during the examination. In such a situation, the main thing is to remain calm, the doctor will prescribe the necessary drugs and, if necessary, send you to the hospital.

Another no less sad reason is a frozen or ectopic pregnancy. I note that it is extremely important to detect this in time, since when an inflammatory process can begin, which will require a long treatment. An ectopic pregnancy is more dangerous for a woman's health, while the fetal egg is fixed in the fallopian tube. It grows, it becomes cramped, and the pipe breaks. All this is accompanied by severe pain and bleeding. Depending on the situation, the woman will be operated on or scraped.

The situation when there is pregnancy, and the test is negative, can occur when taking hormonal drugs, violations of the functions of the woman's reproductive system. In any case, you need to contact your gynecologist for further examination and treatment.

What to do to know for sure

If the test shows one strip, but you have signs, then you need to take a pregnancy test - blood for the presence of hCG. This diagnostic method is the most informative to date. Blood is donated in the same way as for biochemistry - from a vein. The result will be known in about 3-7 days.

You should know that a negative pregnancy test is caused by many factors. The reasons are both in the pathologies of the body, and in hormonal processes. Let's see why there may be a negative pregnancy test.

Information about the term at any time of the day what is it


If you are wondering if pregnancy is possible with a negative test, most likely your health is not going so smoothly. There are several reasons.

Physiological include:

  • inflammation of the internal genital organs;
  • various diseases;
  • feature of the female body.

It is best to contact a specialist who will explain why there is a pregnancy, but at the same time the test is negative. Sometimes this happens due to the presence of benign and malignant formations.

Here you need to thoroughly understand the problem, because you may be trying to understand the reasons for which a negative test is observed during pregnancy, but in fact, inflammation of the ovaries caused the delay in menstruation.

Various diseases of the body can cause a negative result of the test used. For example, if you have all the symptoms of pregnancy, and the test is still negative, the problems may have arisen due to thyroid disease or disorders of the hypothalamus.

Negative result

Certain features of the body can also cause a negative test result. These include a small amount of the hormone human chorionic gonadotropin, the level of which decreases after conception or in the early stages of fetal development. That is why some tests will not be able to detect changes in the body.

Reasons for this result

Sometimes girls search the Internet for photos of various negative pregnancy tests in order to compare the degree of manifestation of the strip, because even a barely visible strip can indicate conception. This may be due to a defective test.

Therefore, if you are sure that conception has occurred, and the test stubbornly shows a negative result, try another express analysis. You can also donate blood to determine the level of hormones. This is the most reliable result.

The test may show a negative result during pregnancy if it has not been stored properly. For example, in a room with high humidity, very high or low air temperature. Sometimes the cause is damaged packaging.

Expired device

Please note that good tests are always packed in two packages. One of them is cardboard, and the other is made of air and waterproof material. Also in the package should be a special bag with filler, which takes away excess moisture. If you have all the signs of pregnancy, and the test showed a negative result, check the date of manufacture. Violated storage periods are also the cause of an incorrect result.

The test can be negative when pregnancy occurs if you do the procedure incorrectly. Read the instructions for use carefully. If you make mistakes, repeat the diagnosis again. This can happen if you use stale urine or test in the evening when hormone levels in your urine are not as high as in the morning.

Also, the result is affected by a large amount of liquid drunk at night, a single or prolonged use of medications.

A negative test result during pregnancy occurs with early testing. This happens because the fetus is not fully entrenched in the wall of the uterus. This process takes from a week to 12 days. Sometimes there is a slight bleeding, which girls take for the beginning of menstruation.

Definition at home

So, now you understand whether pregnancy is possible with a negative test result. If you are afraid of running into a fake, try folk remedies.

Tests appeared relatively recently, so our grandmothers and great-grandmothers had to look for alternative methods for determining conception.

  1. With urine.
  2. With the help of a pulse.
  3. With the help of a bow.

For the first method, you need to take a small amount of urine. In it you need to moisten a piece of paper and drop one drop of iodine on it. If the iodine turns purple or lilac, then the result is probably positive. With a negative result, the color of iodine gives blue.

If you are sure you are pregnant but the test is negative, pay attention to the color of your urine. It is noticed that in the morning and in the evening the urine of pregnant women is highly concentrated, as a result of which its color is dark yellow. In addition, it contains hormones that have a beneficial effect on the growth of flowers. Collect night urine and water garden flowers with it in the morning. Watch the flowers. During pregnancy, they become lush and beautiful. This is a playful way, but it can help out if there are no periods, and the pregnancy test done is negative.

Inflammation of the genitals

If there is a delay in menstruation with a negative pregnancy test, diagnose with a pulse.

  1. You need to lie on your back and touch the place that is 6-8 centimeters below the navel.
  2. Lightly press your hands to your stomach.
  3. If you feel a pulsation, then pregnancy has come.

There is another funny way of determining pregnancy, popular among our ancestors. Plant two bulbs in two glasses and guess that one glass is pregnancy, and the second is not. This method is not fast, because you need to wait until the bulbs germinate.

As soon as the first of them reaches four centimeters, the answer becomes obvious. It is worth noting that these methods are more playful and do not show a 100% result, so if you want to get an accurate answer, it is best to take a blood test or do an ultrasound.

Reasons for the absence of menstruation

A negative pregnancy test with a slight or prolonged delay may indicate either problems in the body or with the test, or the absence of conception. There are several reasons for irregular menstruation.

One of the most common factors is stressful situations, as well as excessive physical activity. You should not do marathon running, powerlifting or choose a "male" job.

Remember that the minimum weight of a middle-aged woman should be about 45 kg. Don't go on strict diets. The body must fully receive vitamins, trace elements, carbohydrates, proteins, fats.

Diseases of the internal organs can also cause hormonal disorders and cause a delay. There are some of the most common diseases that affect the menstrual cycle.

  1. Oncological pathologies of the appendages, uterus.
  2. Adnexitis.
  3. Salpingoophoritis.
  4. Ovarian dysfunction.
  5. Endometritis.
  6. Endometriosis.

With prolonged use of medications, monthly failures may occur. These include cytostatic and diuretic drugs, antidepressants, hormones, anabolics, corticosteroids, antipsychotics, antiulcers, anti-tuberculosis drugs.

Could it be endometritis?

Problems cause chronic intoxication, which arise due to the use of narcotic substances, alcohol abuse, nicotine, work with radioactive, chemical substances in hazardous industries.

Termination of pregnancy entails hormonal changes. And when scraping, there is a risk of getting a severe injury to the mucous membrane of the uterus, which will cause a delay. Use emergency contraception as little as possible. They negatively affect the body and can bring down the cycle. Hormonal contraceptives suppress ovarian function, so there may be delays after stopping them.

The cycle is interrupted due to a sharp change in climate. Do not be surprised if, after a vacation by the sea in a hot country, the body will “reward” you with a violation of the menstrual cycle.

Sometimes the reason lies in heredity, when periodic delays are observed in several generations of women. Talk to your mom or grandma. Perhaps they suffered from the same problem.

The most common cause of delay in women over 40 is menopause. At this age, reproductive function begins to fade, so ovulation either does not occur at all, or is often delayed by several days and weeks.

In any case, in order not to think about whether there can be a pregnancy with a negative result of the test, consult a gynecologist. He will direct you to the appropriate tests that will give an accurate answer.
