I just found out the other day that I'm around 4-5 weeks pregnant, but in the past month I drank once, done pills a couple times not that many,, and smoked weed & cigarettes before I knew anything about being pregnant. I'm not doing anything like that anymore but will me doing it all before now effect the baby at all?? If I knew I was pregnant before I wouldn't have done anything like that and it's really freaking me out. Does anyone know anything that could help ???
