How can I deal with painful ovulation periods?

Dear Doctor, Unlike most women, my menstrual period is not painful. Besides having to change my pad, my period comes and goes without me even noticing. I wish that I could say the same for my ovulation period. I literally feel sick. I have painful cramps and my mood is that of an extremely irritated person. While I know how to get relief should I have a painful period, I don’t know what to do when ovulation is painful. What causes this and how can I deal with it?
