Drugs taken before pregnancy mainly affect the ovulation function of women's ovaries and the quality of follicles. When drugs taken lead to abnormal ovarian function, abnormal ovulation or poor quality of ovulated eggs, normal pregnancy cannot be achieved, which may lead to miscarriage and stillbirth in early pregnancy. If drugs are taken before pregnancy, but the embryo develops well after pregnancy, There is no abortion or stillbirth, which means that the drugs taken have no obvious adverse effects on the quality of ovaries and follicles, and can continue pregnancy without special treatment for the time being. Only during pregnancy, pregnant women need to strengthen prenatal inspection to timely understand and evaluate the fetal development. At ordinary times, attention should be paid to ensuring that all kinds of nutrients are taken in a balanced and comprehensive way to meet the needs of the baby's growth and development. Attention should be paid to avoiding exposure to radioactive damage or chemical poison damage.
