If hCG rises after a miscarriage

Diagnostics

The doctor confirms a spontaneous miscarriage in the presence of appropriate symptoms and the results of examination and ultrasound. Using a gynecological examination, the condition of the cervix is assessed, discharge or bleeding from the cervical canal, and expulsion of the remnants of the fertilized egg are detected. During a bimanual examination, the size of the uterus, its consistency, and tone are determined.

During an ultrasound examination, signs of a miscarriage are established: there is no embryo in the fertilized egg, the placenta is exfoliated, the size of the embryo does not correspond to the term, there is no heartbeat in the fetus.

Differential diagnosis is carried out with anovulatory uterine bleeding, tumor diseases of the reproductive system, hydatidiform mole, and ectopic pregnancy. If the need arises, the following may be prescribed: colposcopic examination, biopsy, culdocentesis, laparoscopic examination.

Laboratory diagnostics are also important in diagnosing a miscarriage. The list of required studies includes:

general blood analysis;
determination of the concentration of chorionic gonadotropic hormone in the blood;
determining the level of progesterone in the blood;
determination of the Rh factor;
determination of fibrinogen concentration;
bacterial cultures of blood, urine, biomaterial obtained during curettage, if an infected abortion is suspected;
cytogenetic analysis of the remains of the ovum in the case of habitual spontaneous miscarriage.

In some cases, when clinical symptoms have not yet made themselves felt, the basis for assuming a diagnosis of spontaneous abortion or missed abortion is too low a hCG level. In the early stages it will be 3-9 times lower than during normal pregnancy. During dynamic observation, no growth will be noted.

With the normal development of the gestation process, with hCG less than 1200 mU/l, the indicator will double after 2 days; with hCG up to 6000, the doubling will occur every 4 days.

What is the difference between an hCG test and a threat of miscarriage in the early stages? If the pregnancy does not develop or has an ectopic localization, then such a pattern is not observed. The hCG level will not tend to increase, but will gradually decrease.

It’s best to ask a specialist how quickly hCG drops after a miscarriage. It happens that after a miscarriage, hCG increases, but this is not at all an indicator of a developing pregnancy. The hormone is secreted by the membrane of the fertilized egg and sometimes even if the embryo dies, hCG continues to be produced for several weeks.

How quickly the hCG drops after a miscarriage will primarily depend on whether the abortion occurred spontaneously. If the fertilized egg has left the uterus, the hCG level will soon drop. And if the pregnancy is frozen and the embryo does not come out, then the hCG level will be at a normal level for some time, decreasing over the course of a month.

A single determination of hCG will not allow you to draw the right conclusions, which is why it is necessary to donate blood for analysis over time in order to identify deviations in time and take the necessary measures.

The death of the embryo may not result in a miscarriage. In some cases, the fertilized egg is retained in the uterine cavity due to degenerative processes and insufficient motor abilities of the myometrium. This condition is called frozen pregnancy.

In case of non-developing pregnancy and incomplete miscarriage, the following methods are used to cleanse the uterine cavity:

medicinal - up to 6 weeks of gestation;
vacuum aspiration - up to 12 weeks of gestation.

After this, to confirm that there are no elements of pregnancy left in the uterine cavity, an ultrasound examination is performed 10-14 days after removal of the fertilized egg, and the level of human chorionic gonadotropic hormone is observed in dynamics.

To prevent infectious complications, antibacterial drugs may be prescribed. This issue is resolved on an individual basis.

A study of the level of hCG is necessary both for the timely detection of miscarriage and for determining the effectiveness of cleansing the uterine cavity after its medicinal or aspiration emptying.

It should be understood that a single case of spontaneous miscarriage is not a reason to despair, and the likelihood that a woman can give birth is still high. If miscarriages are repeated 2 or more times, then a diagnosis of “recurrent miscarriage” is made. After this, an examination is carried out to identify the causes, and then measures to correct this condition are prescribed.

With the normal development of the gestation process, with hCG less than 1200 mU/l, the indicator will double after 2 days; with hCG up to 6000, the doubling will occur every 4 days.

HCG after abortion: norm by week

Pregnancy is a process in a woman’s body that completely restructures its usual functioning. The development of the embryo makes itself felt within a week after its conception. The most pronounced change is the onset of active secretion of chronic gonadotropin (hCG).

This substance is of great importance during pregnancy, therefore, even after its interruption, tests for hCG are very important. This topic is covered in more detail in the material presented below.

HCG - description and meaning of the hormone

HCG is a hormone that is produced by the membrane of the embryo after fertilization

HCG is a hormonal substance that is produced by the outer membrane of the embryo (chorion tissue). During the development of the fetus, this membrane smoothly transforms into a full-fledged placenta. By its nature, hCG can be classified as gonadotropic hormones, common in the internal genital organs of a woman - the ovaries. In its structural composition, the substance has 237 protein structures and a number of other biological subunits.

The increased secretion of hCG during pregnancy is caused by the fact that the female body must adapt to a new way in its functioning. The hormone actively interacts with all organs that are somehow involved in the pregnancy process and perform certain functions. HCG is a more biologically active substance than ordinary sex hormones. It provokes a change in the functioning of the uterus and ovaries, as a result of which the production of progesterone increases. The latter is very important for the development of the fetus, as it supports the process of its development throughout pregnancy.

The main functions of hCG are:

protection of the developing embryo
formation of the placenta
provoking the secretion of a number of other hormones
facilitating the female body's adaptation to pregnancy
reducing stress in pregnant women

In general, hCG is one of the most important hormones during pregnancy, the level of which should always be within certain limits. Improper secretion of the substance negatively affects the condition of the embryo, which can cause unpleasant problems in the future.

Diagnosis and norm after abortion

Within 2-3 days after the abortion, the hCG level should correspond to the gestational age

As it became clear from what was written above, the beginning of pregnancy activates the secretion of hCG in the woman’s body, after which its level in the blood and urine is within certain limits. After termination of pregnancy by abortion or miscarriage, the concentration of the hormone remains above normal, but decreases over time. A similar phenomenon is observed due to the fact that the amount of the previously released substance is quite large and cannot disappear immediately after termination of pregnancy.

The level of hCG in the blood and urine returns to normal only after 5-7 weeks after termination of pregnancy. During the first week after an abortion, the hCG norm is the same indicator that is considered normal for the current pregnancy at the stage when it was terminated.

After 5-7 days after termination of pregnancy, the hormone level will begin to fall and by 5-7 weeks of “decline” it should completely return to normal.

In order to determine how low or high hCG is in a particular case, immediately after an abortion, it is necessary to compare the test results with those presented below:

There are two ways to check hCG levels after an abortion: a urine test or a blood test. It is worth understanding that if pregnancy is terminated at 1-5 weeks, the level of the hormone in the urine will not correspond to the real one contained in the blood.

Therefore, in case of early termination of pregnancy, the only reliable way to check the level of hCG is a blood test. Starting from the 6th week, the concentration of hCG in the urine and blood becomes the same, so you can resort to both methods of testing. It is important to take tests with the preparation prescribed by the doctor. As a rule, blood or urine sampling is carried out in the morning and on an empty stomach.

High hCG level after abortion - reasons and what to do?

Based on the information presented above, a high level of hCG after an abortion is the norm. However, this norm must be within certain limits.

Often, the indicators of a woman who has had an abortion remain too high immediately after the termination of pregnancy, and even after some period of time after that.

There may be several reasons for this outcome of events:

The embryo was not alone. In this case, the previously established default rate should be increased by as many times as the embryos develop. This phenomenon is absolutely normal, so the level of hCG in the blood or urine will fall much more slowly.
An incorrect gestational age was determined. In such a situation, you just need to wait a while, because it is not always worth relying on data on the duration of pregnancy from doctors. They are people too and can make mistakes.
A pregnant woman took synthetic hormones before or after termination of pregnancy. These substances disrupt the body’s normal hormonal levels, so hCG can break down noticeably more slowly than in other cases.
The presence of certain diseases in a pregnant woman (diabetes mellitus, late toxicosis, etc.). It is worth understanding that any illness occurring in the human body can in one way or another slow down the breakdown of hCG.
The fetus had some developmental defects. In such cases, hCG is produced in larger quantities during pregnancy than is normal. Accordingly, it will be eliminated from the body noticeably slower.
The embryo survived the abortion or some parts of its shell remained. This phenomenon, in a completely normal mode, will provoke increased secretion of hCG.

You can learn more about hCG from the video:

Having determined the exact cause of excessively elevated levels of the hormone or the lack of its breakdown, it is necessary to eliminate the factor provoking this phenomenon. So, for example, if the embryo has not died, a repeat abortion is performed, and if parts of its membrane remain, the uterus is curetted.

It is worth understanding that specific symptoms of an abnormally high level of hCG in the body will not appear. This is why it is extremely important to undergo several blood and urine tests within a month after termination of pregnancy to ensure that the abortion was successful. In general, all questions regarding hCG levels after an abortion are easy to answer if you carefully study this topic. The material presented above fully reflects reality, so remember it and highlight what is important to you.

FAQ

Of the millions of pregnancies that end in miscarriage every time, yes, less than twenty percent are actual pregnancies, while others are known as chemical pregnancies. This means that the pregnancy was terminated before it was discovered or confirmed. However, sometimes women may still experience pregnancy symptoms such as morning sickness after a miscarriage. In this case, they may be persuaded to take a pregnancy test. This article will explain what it means if you take a positive pregnancy test after a miscarriage.

Can a pregnancy test show a positive result after a miscarriage?

As strange as it may sound, a positive pregnancy test is indeed possible after a miscarriage. However, in almost all cases this is a false positive result.

Common Causes of a False Positive Test After Pregnancy Loss

Here are some of the common reasons for a false positive test after pregnancy loss.

Presence of hCG hormones

HCG is constantly produced by the placenta during pregnancy and is responsible for the early development of the fetus. However, since miscarriages are usually sudden, it takes some time for the system to reset. During this period, hCG may still be produced and may result in a positive pregnancy test.

Incomplete miscarriage

In some cases, the miscarriage may be incomplete. That is, a fragment of the egg may still be in the uterus. This scenario can also result in a false positive result. A positive pregnancy test 8 weeks after a miscarriage indicates that it was incomplete.

Molar pregnancy

A rare condition known as molar disease or molar pregnancy can cause a false positive pregnancy test result. This condition is a type of gestational trophoblastic disease and comes in two types.

In a complete molar pregnancy, there is no embryo or normal placental tissue. In a partial molar pregnancy, the embryo and normal placental tissue are present, but the embryo is abnormal and malformed.

Molar pregnancy has dangerous complications, including cancer, and requires immediate treatment.

Other possible reasons for getting a positive test after a miscarriage

Some other reasons why you may test positive after a miscarriage:

It is possible to become pregnant again if you have been sexually active since a miscarriage, especially during your first menstrual cycle. In this case, you may actually have a positive pregnancy test, but it requires confirmation from a blood test.

Some medications may also cause a positive pregnancy test, such as Pregnyl or Profasi, as these medications contain hCG.

Kidney disease may be the cause due to the release of protein into the urine.

What to do if the pregnancy test is positive after a miscarriage?

Ideally, you should double-check by taking a pregnancy test using strips from different companies.

You can then ask your doctor to do a blood test that measures the absence or presence of the hCG hormone in your body, as well as the current level it is at. This test should be done approximately two weeks after the miscarriage.

In very rare situations, a pregnancy test that remains positive after a miscarriage may mean that you had a multiple pregnancy, where only one embryo was miscarried and the other is still alive.

What does a positive pregnancy test mean 12 weeks after a miscarriage?

A positive pregnancy test around twelve weeks after a miscarriage is almost certainly because you are pregnant again. However, this only applies if you are sexually active and want to conceive.

How long will it take for a pregnancy test to be positive after a miscarriage?

The standard operating principle of strips for pregnant women is visual. After you urinate, one line means you are not pregnant, while two lines mean you are.

Since modern pregnancy strips are very accurate, they can show a positive result even weeks after a miscarriage due to the small amount of hCG circulating in the body.

When can you get pregnant after a miscarriage?

Getting pregnant after a miscarriage is not difficult. In fact, the chance of pregnancy immediately after a miscarriage decreases by only five percent. In the past, it was believed that pregnancy within 6 months of miscarriage was associated with complications such as stillbirth and toxemia. However, modern research shows that there is no risk associated with pregnancy immediately after a miscarriage.

If pregnancy tests show a consistently positive result after a miscarriage, it is best to consult a doctor. In most cases, this is a false positive test and will not have complications.

However, as the article explains, there are some rare options that can have a serious impact on your health. Getting a thorough examination is important.

Also, if you experience persistent bleeding, vaginal discharge, fever, or pelvic pain, see your doctor as this may indicate an infection.

Positive pregnancy test after abortion

The doctor said 20 days can be positive. I got a plus sign on day 27. I took a hospital test today, the results will be out tomorrow. Previously, the doctor frightened me with the possibility of degeneration of the fetal remains, namely, hydatidiform mole or uterine cancer. Has anyone heard anything about this?

The people attacked the author. She’s probably just checking whether the hCG remains in her body, and not suspecting a new pregnancy.

I had an abortion for medical reasons. The fetus was not viable. A repeat pregnancy was ruled out; somehow I didn’t even think that I needed to write about it. It’s just that, given my rich negative experience (ectopic, miscarriage), I listen to everything that happens in the body, and maybe. Sometimes too much knowledge is harmful. The fact that I’m a fool - somewhere I agree, so thank you everyone for the answers

A repeat hospital test showed a hCG level corresponding to the first week of pregnancy. The doctor said it was either falling slowly for some reason, or it was a hydatidiform mole. They will observe until it drops to 0, do a test every week, since hydatidiform mole can develop into uterine cancer. She had one such case, the woman was observed for a year, then she was eventually given chemotherapy.

The reason turned out to be the most banal, which I ruled out from the very beginning, since I trusted the doctor 100 percent. And she just cleaned me BADLY. I went for an ultrasound to another doctor, there were a lot of remnants of the fertilized egg, she said they might come out on their own. or maybe not, it’s better not to risk it, they cleaned it a second time, everything seems to be fine.

On December 15th I had an abortion, a month later I didn’t get my period, I took a test on January 21st and it was positive, although I was using contraception. The doctor told me to inject progesterone. What could this be?

On May 7 I had an abortion, on June 5 I checked the test because... all the symptoms remained throughout this month, I got scared and now I don’t know what to do, I’ll

Pregnancy test after miscarriage

Nowadays, determining a possible pregnancy is not difficult. Pharmacies are replete with various tests, ranging from the most affordable “strip” tests to the more expensive “ultra-precise” inkjet analogues.

The operating principle of the express test is known to everyone: we take a portion of morning urine and “immerse” the test in it to a certain point. The appearance of one stripe means that there is no pregnancy, and a positive test will be “double striped.”

The test reacts in a similar way to the presence of the pregnancy hormone in the urine - human chorionic gonadotropin, which begins to be produced after the fertilized egg attaches to the wall of the uterus.

However, women often wonder why a test after a miscarriage shows pregnancy? If the embryo is no longer in the uterus, for what reasons does the test “produce” two stripes instead of one? Let's take a closer look.

how long do tests take after a miscarriage?

If M. arrived on time, and you think. that this is a miscarriage, then after the idea of a miscarriage at this period. There wouldn't be any stripes anyway. HCG drops very quickly, and at this time there is nothing to drop. Therefore, this is either some kind of dysfunction. or Pregnancy through M. I had a miscarriage, I miscarried at 7 weeks of pregnancy, the hCG you understand is already in the region of 10,000-15,000 thousand, at the time of the miscarriage it dropped to 900, after cleaning. and that’s already up to the first hundred. Therefore, I honestly think that this is not a miscarriage.

It seems to me that I lost it, because the BT is low. And who knows?!

interesting! Then we can assume, judging by your stories, that my hCG is so dull? Or progic is failing me and there is still hope.

What worries me is that the bleeding was scarlet. and I read a lot about M. through the fetus, but the key factor there was scanty brownish discharge..

yeah. and BT fell. (then why have they been striped for so long.

The doctor told me to lie down until Monday and not breathe. My friend had her period, but in the next cycle it turned out that she was already 9 weeks old))

Yes, hCG can be stupid and even VERY stupid. Now in practice this occurs quite often. For some, with biochemical B., hCG can rise to as much as 100 or higher.

In my opinion, tests should not be trusted, only hCG and ultrasound!

I was told that after the miscarriage the test will be positive for another 2 weeks.

Everything is individual. But for a miscarriage, something bleeds for a long time. Although maybe at the beginning the threat was simple. Give HCG. But BT is low, B has failed or was biochemical.

The story is almost the same as yours! In the same way, after the menses I began to bleed. In short, my test was streaky until my next period. Moreover, even after a miscarriage had already taken place, the hCG in the blood continued to grow! The doctor told me that this happens, that there is a miscarriage, but a piece remains in the endometrium and therefore the hCG increases. HCG also does not fall in one day, but gradually (again, I speak from my own experience, after a miscarriage I donated blood every 2-3 days for 3 weeks, my hands were like those of a drug addict). What is curious: all the tests were weakly positive even when the hCG was about 300. During the tests, neither increasing nor decreasing dynamics were visible.

Features of changes in hCG levels during normal and frozen pregnancy

HCG, or human chorionic gonadotropin, is a hormone that begins to be produced in significant quantities in the female body only after the embryo attaches to the wall of the uterus, which is observed around the fourth day. It is the concentration of this substance in the blood that makes it possible to determine whether pregnancy has occurred.

HCG acts as a corticosteroid, helping the expectant mother’s body to withstand stress and not perceive the embryo as a dangerous foreign body, and also affects the production of progesterone and estrogen, which allows for a normal pregnancy.

Analysis for hCG, norms in humans

A blood test for human chorionic gonadotropin provides the most accurate early pregnancy test. All home tests are also based on this principle, but the required amount of the substance in the urine is achieved much later than the required concentration in the blood.

During normal gestation, the amount of the hormone should double every two days, and by the tenth to eleventh week of pregnancy it reaches its maximum. After this period, the concentration gradually decreases.

Normal concentrations in non-pregnant women and men are zero to five. In pregnant women, the dynamics of hCG begins to increase rapidly and then gradually decrease:

During the first trimester, the level of the substance increases rapidly - from 26 mU / ml to 300,000, which helps prevent miscarriage;
The second trimester is characterized by a slow drop in hCG levels from 300,000 to 3,000.
The third trimester allows the body to produce relatively small amounts of the hormonal substance - the concentration can range from 2500 to 78000 mU/ml.

The table for the growth of hormone concentrations in pregnant women is as follows:

Why determine the level of hCG in the blood?

A blood test for hCG allows you to diagnose pregnancy several days earlier than the test strip “feels” it, that is, from approximately the 5th - 6th day after conception. In the future, based on the level of hCG and its growth rate, one can judge whether the pregnancy is developing normally or whether there are deviations.

An hCG test allows you to confirm or refute the diagnosis of pregnancy and suspect abnormalities in its course. The test for the presence of hCG in urine (qualitative) is used in pregnancy test strips. A blood test can determine not only the presence, but also the exact value of hCG, which is more important and indicative.

In the first weeks, its concentration doubles every one and a half to two days, and reaches a maximum at 10–11 weeks. Then the level of hCG in the blood begins to gradually decrease. This happens after the placenta begins to work independently and takes on the function of a hormonal center.

HCG is included as a component in a double and triple screening test, which is performed at 10–11 and 14–15 weeks and helps to identify possible deviations in the child’s development and hereditary anomalies.

HCG level too high

Any deviation from the normal concentration of the hormone in the blood is fraught with various diseases and complications. Elevated levels of the substance in the blood of non-pregnant women and men may be a sign of abnormalities that a person may have, such as:

Tumors in the testicles;
Tumors in the gastrointestinal tract;
Abnormal growths in the lungs, uterus, and kidneys;
Hydatidiform mole, in which conception occurs, but the chorionic tissue begins to form bubbles rather than a full-fledged embryo;
Chorionic carcinoma is a malignant tumor, most often formed from fetal cells (sometimes found in non-pregnant women).

Low hCG in pregnant women

Since during the normal development of pregnancy the concentration of the hormone in the blood increases rapidly in the first trimester, an absent increase in hCG in a pregnant woman can become a sign of the following pathologies:

The pregnancy turned out to be ectopic;
There is fading of pregnancy (PG);
Threat of miscarriage if hormone levels drop by more than fifty percent;
Delay in the development of the embryo or its death in the first or second trimester;
Observed placental insufficiency;
Post-term childbearing.

Elevated hCG in pregnant women

You should not think that if hCG is contained in the blood in large quantities, then this is not a sign of pathology. If a woman carrying a child has an increased level of the hormone, this may mean that:

A woman is pregnant with several children, and the amount of the hormone increases in direct proportion to the number of embryos;
The fetus may have developmental abnormalities;
The mother has diabetes mellitus;
Preeclampsia may appear - a dangerous complication of pregnancy, accompanied by convulsions and can be a cause of death among women bearing children;
A woman takes synthetic gestagen hormones.

Planning a pregnancy after a miscarriage

Today, according to gynecological statistics, pregnancy after a miscarriage in the first six months occurs in almost every 10 women. Spontaneous termination of pregnancy in the early stages is a kind of signal that something is wrong with the woman’s reproductive system or her health.

Most miscarriages in early pregnancy occur as a result of genetic disorders of the embryonic organs , which are often incompatible with life. Thus, the body naturally selects healthy embryos. After an unsuccessful attempt to become a mother, the probability of a successful new pregnancy is about 90%.

How to get pregnant after a miscarriage so that trying again does not end in failure? To do this, a married couple must find the strength within themselves and figure out why the long-awaited pregnancy was terminated.

Causes of spontaneous miscarriage

According to statistics, almost 80% of miscarriages occur in the 1st trimester of pregnancy. This fact is due to the high susceptibility of the embryo to environmental factors or the woman’s health condition.

Many women who have experienced such a tragedy at least once are very worried about whether there is a risk that a new pregnancy will end in failure. With 2-3 miscarriages in a row, a woman is diagnosed with “recurrent miscarriage,” however, with the right approach to the situation and proper treatment from an experienced gynecologist, the chance of experiencing all the delights of parenthood increases many times over.

HCG during frozen pregnancy

You should contact your doctor for additional examinations for any suspicious reason; you should especially carefully monitor the appearance of:

Bloody discharge during the first trimester of pregnancy;
Drawing unpleasant pain in the lower abdomen;
An abrupt cessation of toxicosis, especially if it was pronounced before.

If after the analysis it was noticed that hCG is not growing well, it is necessary to exclude the presence of a frozen pregnancy, in which the non-developing fetus dies after some time. Most likely, the doctor will order a test several times, during which it will be determined whether the hCG is rising.

To take the test, you need to come to the laboratory in the morning, blood is taken from a vein on an empty stomach. Most often, you need to undergo a laboratory test for fetal pathology from the fourteenth to the eighteenth week; in case of a frozen pregnancy, hCG must be taken as soon as suspicion arises, having first consulted with the doctor who is observing the patient.

In most cases, with a non-developing pregnancy, hCG does not rise; its level may drop sharply, and the rate of decline will depend on the individual characteristics of the patient’s body. For example, with normal development of the child, the hCG level from the fourth to the sixth week should rise from 20,000 to 50,000, with an abnormality the concentration of the hormone at 6 weeks. may turn out to be equal to the readings of the 4th. In some cases, the level of hCG during a frozen pregnancy may slowly increase, but any specialist will determine that the development of the fetus has stopped, since the growth rate of hCG during a frozen pregnancy is not enough to maintain it.

Most often, this situation cannot be corrected, which is why most often doctors simply recommend waiting until the frozen pregnancy ends on its own; in this case, there is not enough hCG, and when the level drops to normal for non-pregnant women, the uterus contracts and expels the fertilized egg, resulting in miscarriage.

It is impossible to answer 100% the question whether a frozen pregnancy can be resolved through a miscarriage without medical intervention. In most cases, if the problem is not resolved naturally, two methods of interruption are chosen:

Medication, which is used if the period was no more than eight weeks;
Curettage, which is performed after a period of more than eight weeks.

Tests for hCG should be carried out not only as a pregnancy test, but also as a way to determine pathologies in the development of the fetus and the process of bearing a child. If the slightest suspicious signs occur, you should consult a doctor, since in this case there may still be a possibility of continuing the pregnancy.

Positive pregnancy test after abortion: what could it mean?

A positive pregnancy test after an abortion is not entirely normal. Many women think so. Why does this happen?

1. During an abortion, the fertilized egg is removed from the uterine cavity and placenta. And since the synthesis of hCG is directly related to the function of the placenta, its removal leads to a decrease in hormone levels. This process proceeds quite slowly, as a result, two stripes remain for some time after the abortion. Sometimes gonadotropin ceases to be detected 24 hours after removal of the fetus, in other cases a positive result persists even after several weeks. This can happen if even a small piece of fertilized egg remains in the uterus.

2. Sometimes the reason is the low sensitivity of the test used - in this case we can talk about false positive data.

3. The result cannot be interpreted unambiguously, since it is influenced by some extraneous factors:

taking medications, one of the components of which is hCG;
special diet;
renal pathologies leading to the appearance of protein in the urine - it can distort the result.

Considering these factors, a pregnancy test after an abortion several times using strips from different manufacturers.

4. The reason for a positive result is often an ectopic pregnancy, during which the fetus is fixed and begins to develop outside the uterine cavity: in the fallopian tube or ovary.

5. The preservation of two stripes is sometimes due to an abortion using the vacuum aspiration method (the so-called mini-abortion), which is considered the safest, but is not very reliable: it often leaves embryonic membranes that continue to synthesize hCG. The consequence is a positive test result.

6. The source of synthesis of human chorionic gonadotropin can be an ectopic pregnancy, in which the fetus is localized in the abdominal cavity.

7. There are also cases when, as a result of an abortion, the fetus does not die. Its preservation in the uterine cavity causes the appearance of two stripes.

8. Two stripes may remain after an abortion if it was carried out by medication. In this case, antiprogestogens are used, the action of which is based on increasing contraction of the uterus and simultaneous relaxation of its cervix. When using the medicinal method, the probability of preserving the membranes and particles of the fertilized egg is quite high.

HCG after abortion: norm by week

This substance is of great importance during pregnancy, therefore, even after its interruption, tests for hCG are very important. This topic is covered in more detail in the material presented below.

HCG - description and meaning of the hormone

HCG is a hormone that is produced by the membrane of the embryo after fertilization

The main functions of hCG are:

protection of the developing embryo
formation of the placenta
provoking the secretion of a number of other hormones
facilitating the female body's adaptation to pregnancy
reducing stress in pregnant women

Diagnosis and norm after abortion

Within 2-3 days after the abortion, the hCG level should correspond to the gestational age

After 5-7 days after termination of pregnancy, the hormone level will begin to fall and by 5-7 weeks of “decline” it should completely return to normal.

In order to determine how low or high hCG is in a particular case, immediately after an abortion, it is necessary to compare the test results with those presented below:

Some other reasons why you may test positive after a miscarriage:

It is possible to become pregnant again if you have been sexually active since a miscarriage, especially during your first menstrual cycle. In this case, you may actually have a positive pregnancy test, but it requires confirmation from a blood test.

Some medications may also cause a positive pregnancy test, such as Pregnyl or Profasi, as these medications contain hCG.

Kidney disease may be the cause due to the release of protein into the urine.

A miscarriage test is recommended if unusual vaginal discharge or other signs of miscarriage appear.

Before understanding the reason for the last type of result, it is necessary to understand how the test works. A special paper strip is impregnated with a substance that reacts with the pregnancy hormone - hCG. As a result, the color of the reagent changes. If a reaction has occurred, 2 stripes appear.

The first one monitors the quality of the test. Normally, a positive result is characterized by 2 evenly colored stripes. If the second is mild, it is recommended to undergo testing for miscarriage.

The same is done when the test is carried out in the first days of a missed period. At this time, there is an insufficient amount of hCG for full staining.

Doctors' recommendations

To find out the exact result, doctors recommend testing following the instructions. A weakly positive result also appears when menstruation stops - the onset of menopause. This is explained by the fact that during menopause, a certain amount of hCG is constantly present in the female body. This hormone can be detected on a pregnancy test. To get reliable results, it is recommended to use a high-quality system.

After a miscarriage, pregnancy hormone levels decrease. If testing is carried out during this period, the strip will show a weakly positive result. The dynamics of changes in the test are the opposite of those characteristic of pregnancy: a few days after receiving the result, repeated testing will show the absence of pregnancy.

To quickly determine the presence of pregnancy at home, the vast majority of women use rapid tests. It would seem that the very structure of such a test suggests only 2 possible answers, which are 97% likely to be true. However, from time to time there is a third option: a weakly positive pregnancy test. Can it be considered negative, or is there still a chance that the woman is pregnant? And what to do if your test turns out to be weakly positive?

Before understanding the reasons for a weakly positive result, let's understand how the test generally works. The most commonly used is a simple test strip. It is a small strip of paper, impregnated in the right place with a special substance that reacts with the pregnancy hormone - hCG. The result of this reaction is a change in the color of the reagent. If a reaction occurs, the treasured second strip appears.

The first plane is a control plane; it monitors the quality of the test. That is, if the control line does not appear, it does not matter whether a second one appears, since the test is defective and its result is unreliable.

Normally, if the result is positive, both stripes should be colored evenly. However, in some cases, the second one may be weaker in color, this is called a weakly positive pregnancy test.

We remind you that hCG is produced by chorion, which appears in the body only after implantation of the fertilized egg. From this moment, the chorion begins to develop, and the larger it becomes, the more hormone it produces. Accordingly, the amount of hCG is different at different stages of pregnancy.

This is precisely the main reason for the weakly positive

Cause	Why is this happening
Presence of hCG	Termination of pregnancy is always stressful for the body. A miscarriage has a strong impact on the female hormonal system, which simply does not have time to “reform.” The hCG hormone continues to be produced “by inertia” for some time, but its level cannot decrease so quickly. Therefore, it often happens that a test after a miscarriage shows pregnancy.
Incomplete removal of the fertilized egg	In this case, the appearance of two stripes may be explained by the fact that as a result of a miscarriage, part of the fertilized egg continues to be in the uterine cavity.

Based on the above reasons, a pregnancy test may show a false positive result. The “blame” for this is the hCG hormone, the level of which decreases rather slowly, as a result of which sometimes “remnants” of the hormone are still present in the body for a month after a miscarriage.

It turns out that the test only shows the presence or absence of hCG in a woman’s body, so even a small amount of it is sure to “light up” in the form of a second strip.

Woman sticks to a diet
The test was carried out while taking medications containing the hCG hormone (Pregnil or Profazi). The fact is that “traces” of the effects of these drugs remain in the body for approximately 10 or 14 days after completion of use
Presence of kidney disease, in which protein is released into the urine
The miscarriage did not end with the death of the fetus. In this case, the woman actually remains pregnant, since the fertilized egg is still in the uterine cavity. Therefore, it is quite natural for a positive result to appear in the form of two test strips.
