Ovarian cysts anyone?

I haven't had a period for a year and a half. Though I crave sex so much, I'm scared of it right now because it hurts my ovaries. I could be just doing nothing and I will feel like a very light stab in my ovaries. My hormones are out of control and getting acne. I know that plays a huge part in me, not being able to get pregnant, even though the doctors say it's possible to get pregnant. Well why haven't i? I wouldn't want to anyway until I have my problem solved.
