When a woman does not plan her pregnancy, then in seventy-five percent of cases of fertilization of an egg results in miscarriage. Such a short-term pregnancy is called biochemical, because it is impossible to determine it by ultrasound or when examining a doctor. And she does not show any signs of pregnancy, because the period of her course is too short. Biochemical pregnancy can be seen only after the analysis of HCG blood . The level of chorionic gonadotropin in the blood makes it possible to determine the duration of pregnancy on the sixth day.
Biochemical pregnancy - signs
There are no signs of a biochemical pregnancy. It can be determined only if a woman is pregnant and at the first day of delaying menstruation will go to the hospital to take a blood test for hCG. If the pregnancy is delayed for a longer period than six days, then it can already be seen on ultrasound. If the pregnancy is diagnosed by the above-mentioned term with the help of the analysis for chorionic gonadotropin, then it is good. But if in this analysis, six days after the pregnancy was detected, the result was negative, then this indicates a pregnancy termination.
Symptoms of biochemical pregnancy
In a biochemical pregnancy, conception is carried out in the same way as in the usual cases of fertilization. That is, the egg normally reaches the limits of the uterus and can even fit into it. But then such a pregnancy is suddenly interrupted and occurs until the moment when it can be determined with the help of ultrasound.
As a result of this process, the menstrual cycle can be delayed in a week and pass more painfully. But often it happens that there are no unusual sensations. Therefore, a woman may even not know that she was pregnant. A blood clot with a fertilized egg can not be noticed, especially if the pregnancy is unexpected.
Causes of biochemical pregnancy
As a rule, in almost all cases the reasons that led to the breakdown of pregnancy at such an early date remain unknown. Some think that such a result may be affected by toxic factors, but this can hardly be true at that time.
Most likely, biochemical pregnancy is associated with hormonal disorders, the treatment of which should be carried out immediately after the diagnosis of a particular problem. For example, a shortage of progesterone can affect a woman's condition and lead to a miscarriage.
But this is not the only reason for a biochemical pregnancy. Other factors can influence this outcome:
- features of the immune system;
- blood diseases;
- chromosomal abnormalities;
- thrombophilia;
- autoimmune and immune factors.
All this can lead to the fact that the woman's body becomes more aggressive to the fetus, which is not easy to get accustomed to in the new "environment".
IVF and pregnancy
Many women in modern times have problems with fertilization and the reasons for this may be different. But thanks to modern medicine, there is in vitro fertilization , through which infertile couples can conceive and give birth to a child. Unfortunately, after IVF, the risk of developing a biochemical pregnancy is much higher than with natural fertilization. But even if a miscarriage at an early age and happened, then try to get pregnant with IVF again can be three months after the discovery of biochemical pregnancy.
