Rainbow baby

Krystle • Married. Nursing school. Pregnant.Rainbow baby?.2 Earth babies. 1 Angel baby. ❤️
I had a miscarriage 8/31/13 and I'm 18+5 pregnant with my rainbow baby. I feel so bad because I'm not attached like I should be. I'm so scared of losing the baby. I mean in super excited about the baby abs being pregnant but I'm always scared of miscarrying again. Any help or suggestions? Is this normal?
