Nervous

I’m about 5 weeks and 4 days pregnant, I have a 3 and 4 year old already but about a year or almost 2 now I had a miscarriage. How do you get over the fear of it happening again? I know you can’t control it but I haven’t had much symptoms yet besides sore boobs and now I have a cold so my body aches and hurts. I’m so anxious 😕 I’m trying to stay positive but it’s so hard sometimes
