I just found out that I am pregnant. I didn't know and am guessing that I am around the 4-4 1/2 month area. Because I didn't know that I was pregnant I was going out to drink regularly and I still smoke cigarettes. I started to bleed the day that I would have normally gone out to party and drink. Is that normal or is my child going through withdraws? Is it possible that I have created brain damage to the child unknowingly?
