How to cope with pregnancy after miscarriage?

Ch

Had a missed miscarriage last july & found out 3 days ago I’m pregnant again 🙈 I couldn’t be more happier ❤️ only thing is I’m finding it hard to stay positive and I can’t wait for my 12 week scan ! That’s when I found out last time about my miscarriage! Just wondering if any one else has had the same anxiety and what i can do ? X
