Pregnancy anxiety

Hello there! Trigger warning maybe?

I will be 5 weeks pregnant on Friday,

I am absolutely terrified I am going to miscarry, I had my first miscarriage last September so the pain and trauma is still very much there.

Does anyone have any advice? I know staying calm and not stressing about it is also best, but obviously that’s hard.

Anyone have any things you can do at home to prevent (obviously not fully) a miscarriage? Or any advice at all? Anyone with rainbow babies that could share any story that could ease my anxiety??

Please be nice! Thank you
