Biochemical Pregnancy – Causes, Symptoms and Subsequent Pregnancies

During pregnancy, a woman’s body changes, so it is almost impossible to follow numerous changes. With each trimester, it is as if we can notice a new set of symptoms, and the changes are sometimes noticeable from week to week. Since a woman’s own body suddenly becomes unknown, sometimes fear or panic occurs.

If we can’t trust ourselves, when can we? It is true that the processes in the human body can be very complex , so not understanding the changes we are going through is actually a completely normal phenomenon. The woman’s body undergoes chemical processes to which the body reacts, and such reactions can sometimes be read with a pregnancy test.

What is a biochemical (chemical) pregnancy?

The name “biochemical” comes from the fact that it can be established only by reading biochemical parameters. In this regard, biochemical pregnancy is most often detected through a pregnancy test, which reads beta hCG, or pregnancy hormone in the urine.

Biochemical pregnancy will be read only by tests that are capable of detecting a very early pregnancy , and the result will be positive. These are pregnancies that cannot be detected by ultrasound, because they end very early.

A large number of women are not even aware that they have gone through a biochemical pregnancy, because the embryo is expelled from the body very early, so spontaneous abortion is registered as a regular cycle. It is an astonishing fact that over 50% of all pregnancies are made up of biochemical pregnancies . They are most often found in women who have been trying to get pregnant for a long time, so they use pregnancy tests more often (as soon as the cycle is a day or two late). Most women will attribute the short delay of the menstrual cycle to stress and will not immediately think about pregnancy.

Due to their short lifespan, biochemical pregnancies are often referred to as biochemical abortions (abortions occur even before a person discovers they have been pregnant).

Symptoms and causes of biochemical pregnancy

Biochemical pregnancy often goes unnoticed, however studies reveal certain indicators that can signal the existence of a biochemical pregnancy . This type of pregnancy occurs when the embryo dies before being implanted in the uterus, at the very beginning of pregnancy. Abortion at such an early stage of pregnancy is mainly associated with serious chromosomal abnormalities of the fetus, which are not compatible with life. In addition, congenital or acquired uterine abnormalities and health problems that can affect hormone imbalances can also be causes of biochemical pregnancy.

Research shows that factors such as smoking and the mother’s age can adversely affect fertility and embryo development. Some studies also point to polycystic ovary syndrome as one of the culprits for miscarriage in the early stages of pregnancy.

However, biochemical pregnancy can affect any woman . The condition will be more often detected by women who are struggling with infertility, by the fact that they will use pregnancy tests more often at very early stages.

The symptoms of biochemical pregnancy are generally difficult to notice, since the pregnancy ends before the sixth week. In addition, the symptoms are similar to those attributed to a regular pregnancy (since the pregnancy is real, only short-lived) or the menstrual cycle. Symptoms include : breast tenderness, morning sickness, lack of energy and severe fatigue. Later, when an abortion occurs, severe cramps and pain and increased bleeding, accompanied by blood clots, can occur. A large number of biochemical abortions are identified as heavier menstrual bleeding.

In the past, biochemical pregnancies were not even known, as there were no tests to detect pregnancy at such an early stage. If menstruation is delayed for a couple of days and even a test indicates pregnancy, the gynecologist will probably advise you to wait a few more days before the ultrasound examination . If bleeding occurs, it was most likely a biochemical pregnancy, and the level of beta hCG hormone in the urine and blood will drop in the next few days.

Pregnancy is clinical only when it can be confirmed by ultrasound examination . In the case of a biochemical pregnancy, the ultrasound examination will always be negative. It is possible to notice a slight thickening of the uterine wall.

After a biochemical abortion, most women wonder if curettage is necessary . Since this is a pregnancy that ends at a very early stage (before the embryo is implanted in the uterine wall), there is usually no need for curettage. The uterus will be cleansed naturally – during the menstrual cycle. The menstrual cycle after a biochemical pregnancy may be somewhat more abundant (since it is an early abortion), but in some cases it may even remain regular.

Pregnancy after biochemical pregnancy

It is comforting that biochemical pregnancy does not affect the regularity of the next pregnancy . Of course, if the biochemical pregnancy is the result of certain health problems, there is probably a need for appropriate therapy or intervention. However, the biochemical pregnancy itself does not affect the chance of staying pregnant again and going through the pregnancy without any problems.

The most difficult consequence that such a pregnancy leaves, is grief over the loss of a child and fear that something will be wrong with the next child. In most cases, expectant mothers who have already gone through a biochemical pregnancy and early abortions, become extremely anxious during each subsequent pregnancy. That is why it is very important that they take all possible steps in time , in order to alleviate their anxiety by knowing that their baby is developing normally.

Prenatal testing is possible from the tenth week of pregnancy. My prenatal test is a non-invasive, reliable and completely safe method , which detects chromosomal abnormalities in the fetus. It is enough to sample a small amount of mother’s blood and the results of an extensive analysis arrive after a few days. The test in very early pregnancy reveals the presence or absence of chromosomal abnormalities, as well as the sex of the baby. The results of the prenatal test, which show that there is no reason for concern, will bring peace and tranquility to the life of the pregnant woman and enable a carefree pregnancy.

Prenatal testing is especially recommended for the risk group of pregnant women : pregnant women older than 35, history of miscarriages, burdensome family history, pregnancy caused by in vitro fertilization, unfavorable double and triple test results…

Most biochemical pregnancies come and go unnoticed, because they were terminated before the sixth week of pregnancy. However, women who have been struggling with infertility for a long time, or those who have undergone in vitro fertilization, can understand biochemical pregnancy as their own mistake or failure. For a moment the dream came true, and then it was cruelly taken away. That is why it is necessary to provide support to women who consciously go through a biochemical pregnancy, and psychological counseling is always recommended.
