Hello ladies! So exactly last month I got pregnant and had miscarriage at 7 weeks. I just found out 2 days ago, I am pregnant again! I am extremely happy, but scared to death of having another miscarriage.. As I was reading online a lot of women said that experienced a miscarriage there first pregnancy went along to have a healthy second pregnancy. As well as the chances of you having another miscarriage drop due to you already having one. Has anybody has similar experience or gone through this? I go tomorrow for all my lab work and then Tuesday again before my next apt Wednesday.. My doctor and fiancé think I'm just stressing myself out and worrying myself too much /:
