Did I miss ovulation?

I’m sad because I didn’t test yesterday but I did this morning and had an almost positive OPK. It wasn’t completely positive yet though. I just tested again a few hours later and theirs barely a second line, it’s so faint. Did I miss ovulation? Is it normal for the hormone to fluctuate in a day?
