polycystic ovary syndrome
"This was the first one I was put on after going off b.c. after college when I was able to get married and needed contraceptive. I had known for years that I had PCOS (zero periods/year) and would eventually get my diagnosis 2 months after this b.c. It was horrible. I had major mood swings, I would scream at my husband (then fiance) then all of a sudden end up bawling. I had to go off it and still have yet to find a good b.c. that works."
