Pregnancy after miscarriage

Erin

In had a very early MC on July 5th. I bled for about a week and my pregnancy tests became negative. I got a positive opk about 14 days ago. I got a BFP on a frer then I took a first response digital test that same day and it was negative. I got my beta drawn and it was 24. My ob said it could be a new pregnancy or just residual levels from before and that she would retake my levels in 2 days. Now that was yesterday. Today I took a first response digital and it read positive! Do you think my levels went up?!? I'm sorry for the run around post, I'm just really hoping for my rainbow baby!
