Ovulation after MC ??

Has anyone ever ovulated while getting negative opk? My opk are always on point. But now after a MC I know they are out of wack. I was getting positives when I still had HCG in me of course, but now my HCG is completely gone and my opk’s are negative. But accordingly to glow I should be ovulating now. I know I can’t rely on glow after a MC, so I think I’m just going to BD during “Glows fertile window” and when I get a positive opk just to be on the safe side. Just wanted to know if there was any possibility that I might be ovulating even though opk is negative ? 🤷🏼‍♀️
