I am so scared 😔

Vivian
My husband and I have been trying for a year now. I had a miscarriage back in August 2016 due to the rH factor; I was only 8 weeks, also. And I just got a BFP and I am TERRIFIED of having another miscarriage. I keep thinking, "what if that wasn't the problem?" "What if it happens again?" I'm trying to be hopeful but damn. It's hard. 
Have any of you ladies had the same experience? Or close to it?
