Hcg levels and ovulation?

Leah

I had a miscarriage Feb 19... we had been tracking my HCG levels and as of March 13 HCG was 8.

I also took an ovulation test to see if I was ovulating, the same day, because I was having discharge like I was. It came back that yes, I was ovulating, two clear dark lines.

I thought you can’t ovulate until HCG levels are 0... has anyone else had this?

Edited to add we did BD that same day and day after, so I’m curious if there is a chance we could have gotten pregnant...
