New to OPK

So I am new at taking these test. I know this is negative but I’ve gotten the same result for the last 3 days and glow is predicting me to ovulate this week. Last month AF was 3 days late but I think I might have ovulated right after my period. Is that possible? Or should I just keep testing because maybe I’m ovulating later than normal? I’m hoping that I ovulated right after AF and that I keep getting these negative test because I might be pregnant but that’s only me hoping. I keep getting light cramps/pinching feeling extremely low and it gets tight so I’m praying. I would just like y’alls opinion.
