I had a very difficult first pregnancy I found out yesterday I was pregnant with my second I was told by doctors I would not be able to have even one child. so the second child has taken me away by surprise and I can't stop worrying that I'm going to lose it does anybody know if chances of miscarriage go up if you had a difficult pregnancy in the past. with my first I did not smoke I started smoking when she was around 1 I'm actively trying to quit now that I found out I'm pregnant and I know that can up my chances does anybody have any advice
