Sad. Questionable. Scared. In pain.

Around the general area of my ovaries, I feel this sharp pain. Mainly after having sex. And days after. But in time the pain goes away. I have had ovarian cists since I was younger but I just got off my period a few days ago. My boyfriend and I have sex a few times a week, and don't get me wrong it's great. But sometimes it just hurts already so bad that I want it to just be over with. I feel like it's throbbing when the pain begins. Then the sharpness comes in. I don't know what could possibly be wrong with me. Help?
