So anxious about my Rainbow BFP

Nicola • I`m a 32 year old teacher from the UK. Had my rainbow baby in September 2017 after miscarrying twice. Had a chemical pregnancy in January and now TTC #2
I miscarried in March and got my BFP on Sunday for my rainbow baby. I've been fine until today where I am soooo nervous and anxious. I know stress can cause all sorts of things to change in your body and I'm just really trying to calm myself down. Any suggestions? 😱
