pain in one ovary?

Ashley
Help!
Over the past few hours I've had a pretty bad pain on my left side where I'm pretty sure my ovary sits. I've had a pain like this once before but it ended up just going away on it's own but I never really knew what it was.
I'm currently ovulating (yesterday was my high peak), so I'm not sure if maybe it's just ovulation pain? 
I'm the worlds biggest hypochondriac so I'm freaking out over it. The pain's sort of a dull ache but if I pee it hurts. Idk what it is but it's freaking me out!
I just wanted to see if anyone maybe had anything similar happen and if it sounds like ovulation pains?
Thanks everyone!
