Really need to vent

So my daughter is going to be 2 years old in a few months and we started to talk about having another one All I can think about is the stress I put myself through with my first pregnancy I’m so terrified with a miscarriage my daughter is a rainbow baby I made my self sick bc if I didn’t feel her move I would run to the er I was a nervous wreck the whole pregnancy thinking what if she has a birth defect or something like that (I would love her the same and all babies are a miracle) How can I stop worrying about all of this with my second pregnancy
