From a health perspective, alcoholic beverages are not good for fetal development and may cause fetal malformations, congenital heart disease or miscarriage. However, the fertilized egg in the early stages of pregnancy also has certain self-repair functions. After knowing that you are pregnant, you should stop smoking and drinking, avoid exposure to irritating chemicals, and undergo the appropriate auxiliary tests to see how well the embryo is developing. If both hormone levels are within the normal reference range, an ultrasound should be performed after 42 days of pregnancy to confirm that the pregnancy is intrauterine and that the gestational sac is developing normally, indicating that the previous alcohol consumption has not affected the embryo.
