Pain through ovulation

I should've known that my first cycle ovulating would be painful. I was in bed all day and couldn't get up because the pain was running up one side of my body and down the other on Friday. This was on day 19, which is very late, so I'm not sure what this means. I really think a cyst popped at the same time because that's what it felt like. I'm positive I at least ovulated this cycle after taking many OPK's to find out. Any late ovulaters out there?
