Pregnant an terrified

I am pregnant with my rainbow baby. I am 19 weeks now. But since the miscarriage, every little ache an pain scares me. Everything about this pregnancy scares me. I just want a healthy baby an don’t want to go through that again. I am still not fully over it. My family had so much going on at the time I was not able to grieve properly. I am not sure if I want comforting words or advice. Honestly at this point I think I just need to chill relax an enjoy this one.
