What do ovulation pains feel like?

Cassie • I am 1 in 10- PCOS fighter.
I think I'm having ovulation pains. It happened about 2 hours ago, and was just moderate cramping in my lower abdomen that only lasted about 30 seconds. It happened again about 30 minutes ago. I noticed today that I'm producing more cm. My OPKs are negative, so I'm not sure if I'm actually ovulating or not. I'm on cd 13
