Drinking alcohol in early pregnancy can affect the health of the fetus, but the size of the effect is related to the amount of alcohol consumed. A small amount of alcohol will have a small effect on the fetus, while a large amount of alcohol may lead to malformations and other negative consequences for the fetus. Alcohol is a teratogen that may cause fetal malformations, and both spouses should abstain from alcohol before pregnancy. Drinking alcohol in the early stages of pregnancy may have an effect on the fetus. In particular, drinking a large amount of alcohol may lead to the occurrence of fetal miscarriage, embryonic arrest or fetal malformation. If you have consumed alcohol in early pregnancy, you should go to the hospital and communicate with your doctor in time. You should have regular maternity checkups to keep abreast of the condition of the fetus.
