I need advice😕 is it possible to ovulate after misscaraige while getting a faint line on pregnancy test?

I think I ovulated yesturday, I had a misscaraige 6 weeks ago. I was getting negative opks and then Monday I got a positive and yesturday. I took a HPT today to see if my levels are down and it was faint, so I'm happy. But I've read you can't ovulate until your hcg is 0???? Here's my HPT, and here are my ovulation tests. I've been having EWCM for a few days now
