Ovulation spotting

I did an ovulation test cd11

Didn’t test again until cd14 (I did three)

I’m now cd15 did a test and negative again

I have just wiped and got spotting… im confused does this mean I’m ovulating right now? I don’t get it

I did miss 2 days ovulation tests so could it be the drop in hormone? And I’ve already ovulated

Anyone know what ovulation spotting actually means I’m at a loss
