Hello ladies! So exactly last month I had my first pregnancy and ended having a miscarriage at 7 weeks. I just found out 3 days ago I am pregnant again! At this point I am very scared/nervous too lose this baby.. As I was reading online, a lot of women have said during there first pregnancy with a miscarriage they ended up going to a second healthy pregnancy. And the percentage drops if you have already had a miscarriage. I go tomorrow for lab work and then again Tuesday before my next doctors apt Wednesday.. My fiancé and Doctor just think I am worrying myself sick.. Point is lol, has anybody else gone through this or similar??
