Miscarriages

I’m so scared of having a miscarriage for the second time. For the first I found out I was 1-2 weeks pregnant and then miscarriaged a week later (as my next period seemed to start) but it lasted longer and doctors confirmed I miscarriaged via blood tests :( I was devastated. Just over a month and a half later I find out I’m pregnant again. This time 2-3 weeks. My next expected period is this Sunday so I am absolutely horrified and scared. Being calm for everyone else but I’m just so scared. I don’t know what to do or how to feel. Any advice?
