Opinions?

So I've had irregular periods all my life. I've been with my boyfriend for 1 1/2 years and when we first got together sex was great then all of a sudden out of nowhere a few months ago, things took a turn
I no longer had a sex drive, and sex was painful. 
Thinking it was birth control, I stopped it entirely. Found out it wasn't. My doctors office told me that I MIGHT have ovarian cysts. Honestly. I just want to be able to enjoy sex again and I want it to stop hurting. Also I NEVER know when I'm gonna have a period. All of this scares me because I feel like I'll have difficulties having kids. 
Also: my left ovary hurts so much that It literally hurts to touch on the outside of my stomach
