Drospirenone / ethinyl estradiol
"I was taking this pill for PCOS and heavy periods, and also birth control. While it helped my period become regular (which is very, very nice), and I guess lightened my period (but not by much), the side effects are just too much. I've never had such intense breast pain in my life (I even tested for pregnancy to be sure I wasn't missing something), acne that I never had even as a teenager has been plaguing me, and my mood swings are awful. I switch from happy to angry and depressed within minutes, which isn't like me at all. I'm moving off this pill thank the Lord."
