Drinking during ovulation usually has little effect on pregnancy, but conception under these circumstances can have some effect on the development of the fetus. If you are pregnant, you must weigh the pros and cons and need to have special pregnancy tests, Down’s syndrome screening at 14-20 weeks of pregnancy and 4D ultrasound at 23-26 weeks of pregnancy to detect malformations. If the test is high risk, further amniocentesis or non-invasive DNA testing should be done. If you want to have a baby, you must prepare well for pregnancy, don’t drink alcohol during the preparation period, both spouses should stop smoking and drinking, keep a happy mood, don’t work too hard and create good conditions for conception.
