Rising hcg after miscarriage?!

Emily

We found out we were experiencing our 2nd miscarriage on 7/24. I stopped bleeding about 10 days later. A few days later 8/9 seemed like I had Ewcm and glow said I could be ovulating so we had sex. A week later I felt all my pregnancy symptoms: nauseous and hungover feeling in the afternoons. I took a test, positive. I know it could be a false positive due to Hcg left in my system. Two days later I took another test and it was positive with a darker line. I’ve continued to test every two days and keep getting positives. I go see my OB on Friday.

Do you think it’s retained tissue or new baby? I’m obviously hoping for the latter.
