I understand your concern and I will do everything I can to answer your question. Congratulations. Try not to worry, you are not alone: many moms discover they are pregnant much later than 4 months and usually everything is fine. A few alcoholic drinks are very unlikely to hurt the baby: don t drink any more of course but don t worry that the baby was hurt. The prenatal vitamins (particularly calcium and iron) are mostly important after 4 months. Keep on the vitamins and, again, almost for sure, no harm done. Likewise: exercise and even heavy lifting is safe during the pregnancy. They are very well protected in there and the research is very clear: serious athletes (including marathon runners and weightlifters) have the healthiest babies. Most moms get to a point where exercise gets uncomfortable but you can t hurt the pregnancy with almost any amount of lifting or exercise. I hope that helps and best of luck to you
