How do you stop worrying?

How do you ladies stop freaking out about a MC? I saw baby’s hb on Friday at 7+1 and I’m on progesterone supplements, but with these fluctuating symptoms I can’t help but constantly be freaked out. I had a MC in October after i saw the hb at 6+6 and I keep thinking its going to happen again. I’ve had 3 miscarriages this year and I’m just so worried. One day I will feel like absolute garbage and the next day I feel fine. I’m such a nervous wreck 😫 I just want my rainbow baby! 😪
