What’s this mean??!


Ok, testing started between Sunday and about 20 minutes ago. I started bleeding on 3/12, passed products of conception (pic) at the office on 3/15. They drew HCG on 3/22 (not 3/15) and HCG was 37. By now I thought I’d have negative hcg, but I can see with the naked eye, vf positive. At first I thought I was ovulating, which I do believe. But why the positive HCG?
