Was wondering if any of you knowledgable ladies could offer some help?

I started taking Ethinylo Estradiol on Sat, starting at 30 mcg. My ovaries feel as if they are going to explode, very painfull. Even when doing my last full stim cycle I had 54 follies, and it didn't feel this bad. I haven't had these meds before, and by my information they are supposed to stop the ovaries from producing eggs, so why the pain?

Can any one help?
