Help! ovulation pains while on the pill?

Ne
I'm on the pill. I take it every day, same time. I haven't been sick after taking it ever. yesterday, and the day before, I've had really severe ovulation pain. I never had it while off the pill but it's in the right place, it's really severe and stabbing. this is the third day and I can hardly walk it hurts so bad. am I ovulating? could it be a cyst?!
