Ovulation pain! Ouch!

Cheryl
Sometimes I experience sharp/cramping ovulation pain. Or I think that is what it is. It occurs right when I am expected to ovulate and is on one side only. 
This month it is crippling. Can't stand up to fast and it hurts my left side when I walk. Took an opk test yesterday and it was positive. Pain started today while at work with a sharp pop feeling then cramping/aching feeling like I described the rest of the day. Anyone else have this?
