Hello ladies! So exactly a month ago I had my first pregnancy and ended up having a miscarriage at 7 weeks.. 3 days ago I found out I am pregnant again! At this point I am excited but scared/nervous of losing this baby. As I was reading online, women/doctors were saying that your chances of miscarrying your second pregnancy goes down if you have already had a miscarriage your first pregnancy. I have known a few people who had a miscarriage there first pregnancy and went along to have healthy pregnancys. My fiancé and Doctor think I'm just worrying myself sick lol.. Point is here, has any other wine gone through this?
