HELP! Spotting CD 12

Ch

I've had some spotting and period like cramps today on CD 12. I have never had this before. Google says it ovulation bleeding which I have never heard of before.

My clear blue opk went wrong this morning after if chucked out my pee so I don't know if I have peaked today. 🙄😤 If I did I'm ovulating early so I'm freaking out.

Anyone else had this?
