Ovulation 20 days after withdrawal?

I finished my withdrawal bleeding July 16th, but did not start opk until the app had me start doing them on July 27th.

I kept getting negatives which kept pushing Glow's predicted ovulation day back til it stopped moving and I gave up. I still kept doing the OPKs figuring I just didn't ovulate and my AF would come.

Today is 20 days after withdrawal bleeding and I finally got a positive opk. I'm confused if this would be considered a late ovulation or not since it's post-13 years on BC pills.

Going to cross my fingers and BD anyways!
