What will happen if you take medicine in the first month of pregnancy?

Generally speaking, the period of time when a pregnant woman is just pregnant, especially the first three months, is an important period for the slow development of the fetal nervous system. If the pregnant woman takes some medications at this time, it is likely to have a certain impact on the growth and development of the fetus. However, since various drugs have different effects on the human body, the specific situation varies from person to person, and the specific extent of the drug's impact on pregnant women cannot be predicted.

3 to 8 weeks after fertilization is the period of differentiation and formation of the embryo's organs. It is extremely susceptible to external factors such as drugs, which may lead to fetal malformations. This is a "highly sensitive period to teratogenicity." During this period, do not take any medicine unless it is necessary, including general health products and tonic medicines. If the medication is optional or can be temporarily discontinued, then do not use it. If you must take medication, be sure to use it carefully and safely under the guidance of a doctor. If the pregnancy continues, prenatal diagnosis can be performed between 16 and 20 weeks of pregnancy to further understand the growth and development of the fetus and rule out fetal malformations.

In addition, you can refer to the latest pregnancy drug classification issued by the FDA (divided into five levels: A, B, C, D, and X) for clinical reference in selecting safe medications during pregnancy. Class A and B drugs have no harm or side effects to the fetus and can generally be used safely during pregnancy, such as multivitamins, some antibiotics (such as penicillins and cephalosporins), etc. Class C and D drugs are harmful to the fetus (causing teratogenesis or miscarriage) but beneficial to pregnant women. They should be used with caution after weighing the pros and cons. Such as some antibiotics and hormone drugs. Class X: harmful to the fetus and not beneficial to pregnant women. This type of drugs is prohibited during pregnancy, such as anti-cancer drugs and sex hormones.

However, whether pregnant women taking medicine will affect the fetus depends on the type and dosage of the medicine used. If you want to keep the fetus, pregnant women should undergo regular pregnancy checkups, including Down syndrome screening, four-dimensional color ultrasound prenatal fetal anomaly screening, amniocentesis and umbilical cord blood analysis. These examinations can allow doctors to understand the development of the fetus in the uterus. However, taking some medicines before or in early pregnancy will not have much impact on the fetus, so there is no need for an artificial abortion.
