What birth control pill will help ovarian cysts?

I went to the hospital because I keep getting ovarian cysts and they told me to get birth control. When I went to the gynecologist the nurse and doctor were actually pretty mean to me and they thought I just wanted birth control for sex and didn't listen to anything I had to say about the cysts. They just gave me a three month sample of Loestrin. I believe it worked at first, but now I'm on the third month and I'm pretty sure I have another cysts. What brand of birth control will help stop these?
