Almost 4 weeks?

Haley

I confirmed pregnancy with my doctor today. I had my blood drawn. The number came back as 18 miu’s Should I be worried? I recently had a miscarriage 2 months ago so I’m trying to stay positive but I’d be lying if I said I wasn’t scared. My doctor said I wouldn’t hear from him till Monday but did say we would do follow up bloodwork next week with another 48 hour turn around.
