Always worried !

About 3 months ago I had a miscarriage at 8 weeks the baby stop growing. Now Everytime I have the littlest cramp I run to the bathroom just to make sure I'm not bleeding. I went at 7 weeks 2 days and seen the heartbeat which was amazing. Now I'm so nervous about this one. I'm 8 weeks 1 day. Praying for my little Peanut !
