Ovulation Cramps?!?

Um okay so I've been taking birth control pills for almost 9 months now. Everyday at 10 pm, I've never missed. I've never skipped.

I got my birth control "period" last week and it was normal but there was more clotting for sure. Wasn't too concerned.

But right now I have cramps. Like mild period cramps. Everything online points to implantation or ovulation Cramps.

I had sex before my period but I did have to pee in a cup on Monday at the doctors office and I'm not pregnant. So.... Am I ovulating? And if I am, WHY? I was under the impression that when bc is taken correctly, you don't ovulate. So wtf?
