Recently, it was thought that the pregnancy was on the background of reception of hormonal preparations, it is advisable to interrupt. It was assumed that the teratogenic effect of the pill adversely affects the fetus, causing various pathologies of development of organs, including genital, heart and limbs, as well as possible psevdogermafroditizm. However, recent studies show that in most cases the administration of oral contraceptives has no harmful effects on the embryo and does not cause any abnormalities. However, the hormones included in oral contraceptives, can change the vitamin-mineral balance of an organism of future mothers, in particular, prevent the normal absorption of folic acid, vitamin C and other micro - and macroelements, promote increased absorption of vitamin A, which in large quantities has a toxic effect on the fetus. Therefore, if you suspect pregnancy should immediately stop taking hormonal drugs as soon as possible to go to the doctor and be sure to tell him that for contraception used the pill. When taking oral contraceptives in early pregnancy events can develop in 2 variants. In the first case, which the vast majority, birth control pills do not affect the fetus, the pregnancy is preserved and progresses. In the second embodiment, the hormone can cause embryo damage, as a result of which he dies, and the pregnancy will be interrupted. However, most often this is due to the individual characteristics of the organism of a pregnant woman, a high dose of hormones that is parallel to the other medications that are incompatible with the contraceptive pill, and other negative factors, so to speak unequivocally about the destructive effects of hormonal drugs on the fetus can not. Today the influence of the hormonal drugs on fetal development are understudied. It is unknown whether the administration of oral contraceptives in early pregnancy harm the baby, cause abnormalities in its development or fetal death. Also, there is no reliable data about what fetal abnormalities are associated with contraceptive pills. But in any case, pregnancy is a reason to urgently stop taking oral contraceptives.
