Some women get pregnant after drinking alcohol without knowing it. If they only drink a small amount of alcohol occasionally or drink red wine, the alcohol content is not too much and the effect on the fetus should not be too great. It is recommended that the fetus can be retained, need to follow the doctor’s instructions to do regular pregnancy checkups, especially in about 20 weeks of pregnancy in a timely manner to do four-dimensional ultrasound examination and the Down’s syndrome examination, to diagnose the fetus whether there are developmental malformations, if abnormalities are found, the pregnancy should be terminated in a timely manner. If a woman drinks a lot of alcohol in early pregnancy or has a habit of alcoholism, a large amount of alcohol is likely to have an adverse effect on the healthy development of the fetus, it is recommended that it is best not to keep the fetus for the time being, to avoid the effect of alcohol leading to congenital developmental malformations in the fetus. From the perspective of eugenics, if you plan to have a child, both spouses should quit smoking and drinking six months before pregnancy to avoid adverse effects on the fetus.
