Did I ovulate or not?

Jancy • TTC since Jan 2019: I ectopic, I MC, 1 chemical, two retrievals, 9 (!) embryos on ice and one successfully implanted and due 10/8!

Hiya! Has anyone had an issue with OPK not showing a clear spike, but ovulating anyway? Mine went up and wavered several days, and now glow thinks I’m ovulating tomorrow but he opk today was negative and my temp went up. Did I maybe miss the really high spike? I only tested once a day. Thanks!!!
