Pregnant after miscarriage

So in last year in April I got pregnant and in June I had a miscarriage and now I’m pregnant again(4 weeks &3 days) and scared out of my mind of having another miscarriage. I’m trying to be positive and just enjoy this pregnancy over all. I’m also trying to stay occupied and try not to think about being pregnant but I’m also excited as hell........ so many emotions going on rn and I just trying to take it one day at a time. Can anyone tell me how they stayed calm and not try to worry as much.
