In the early stages of pregnancy, if you drink alcohol will affect the growth and development of the fetus, not serious, it will easily lead to miscarriage, if particularly serious, will lead to intrauterine development of the fetus malformation or stillbirth. Because alcohol is a strong stimulant, it can lead to certain neurological effects during the formation and development of the fetus, but it depends on when the alcohol was consumed and the amount of alcohol consumed, which are all related. If you drink during the formation of the fertilized egg, it will not have a great impact on the fetus, and if it does not lead to a biochemical pregnancy, it does not affect the fetus, so you can safely wait for delivery. If you have been drinking after one month of pregnancy, this situation may harm the fetus, but if you drink especially little, it should not be a big problem, in the middle and later stages of pregnancy pay attention to the Down’s syndrome screening and 4D examination.
