So so nervous

So I'm coming up on 6 weeks pregnant and I can't help but feel terrified that they're not going to see anything at my scan. I'll probably be about 7 weeks at the time of the scan...

I'm terrified of a blighted ovum. So so anxious to the point where I get palpitations. Sounds silly maybe but I had a chemical pregnancy one month before getting pregnant and that was enough heartache for me 😢

Is anyone else absolutely terrified of not finding an embryo or heartbeat? Hoping for a healthy baby and pregnancy 😔

Any words of advice would be appreciated
