Drinking alcohol during pregnancy can have bad effects on the fetus, including teratogenesis, brain development, and miscarriage, but the specifics vary from person to person.
Drinking during pregnancy has a bad effect on the fetus, although it does not always happen, but there are a large number of studies that show that drinking during pregnancy is likely to lead to fetal malformations, neurological damage, affecting intelligence, hearing development and so on. It is generally accepted that the greater the amount of alcohol consumed, the greater the harm, but there is no safe range of alcohol, so it is recommended to avoid consuming drinks containing alcohol during pregnancy.
If you become pregnant unexpectedly after drinking alcohol, you should consult your specialist in a timely manner, complete all tests and other routine obstetric assessments before deciding whether to continue the pregnancy, and avoid re-exposure to alcoholic beverages.
