Ethinyl estradiol / norgestimate
"I started taking this to prevent pregnancy, since I have light, painless periods and no acne. Even after a year, I had acne breakouts every month, significant cramping on my periods, loss of appetite, nausea, and mood swings/suicidal thoughts during my PMS week. I decided to switch after I kept waking up in the middle of the night with severe stomach pain. I'm sure it works fine for some women and it did prevent pregnancy, but the side effects weren't worth it."
