WHY AM I SOO SCARED???

I'm 7 weeks pregnant and I'm so scared of loosing it 😕 I've had a miscarriage 8 years ago and since then I got 2 boys..

Everyone around me is 5 weeks pregnant ahead of me or a few days.. I feel this is more pressure.

I don't have a midwife appointment until Thursday but I can't stop thinking about it. I'm soo gassy either which doesn't help 😕..

Am I over reacting?

(16 is my lucky number as well which doesn't help)

How can I get over this??
