Rainbow baby moms. How long did it take for you to get excited about your pregnancy?

C

I had a missed miscarriage in February, it was my third on and NY first after NY daughter was born. I was abut 14 weeks when we found out. . Found out I'm pregnant again, haven't called my doctor about it, when I think about it I feel so detached from it. I don't want to get excited because I feel like things will go wrong. Is this okay?
