ovary pain??

Allyson
I've been experiencing sharp pain in what I think is my left ovary. It comes and goes and sometimes gets worse when I take deep breaths but not every time. 
Nothing really triggers it, it just comes and goes. 
I know that I used to experience some ovary pain when ovulating but I'm on the pill and I'm pretty sure the pill makes you not ovulate, right?
I had an exam 6 months ago and nothing was abnormal. 
I'm gonna go to the doctor I'm just waiting on my medical card to come in the mail
