Early pregnancy if the pregnant woman with some progesterone and other birth control drugs, amoxicillin, cephalosporins, etc., no effect on the fetus, belong to a relatively safe drugs. While some gentamicin, levofloxacin, streptomycin and other such drugs, may cause fetal malformation. The fetus is basically mature in late pregnancy, and the impact of the drug is relatively small. However, you can’t just use drugs during pregnancy to avoid affecting the fetus. In addition, you should pay more attention to rest during pregnancy, avoid strenuous exercise, and do obstetric examination (Down’s syndrome, 4D ultrasound, etc.) on time to observe the development of the fetus in all aspects.
