Ethinyl estradiol / norgestimate
"I've been taking Sprintec for a couple months and from the first week I started I had horrible acne breakouts.  My periods are longer than they've ever been, even while off birth control and while my cramps aren't as severe during that time I have cramps all the time it seems. At least 3 weeks out of the month.  I have horrible headaches and feel like I might pass out, although I can't say for certain these are from taking Sprintec.  The worst side effect of all is my mood swings. It's sad and scary when out of the whole month the time that I'm the calmest is during PMS and my period.  I snap and get upset with friends, family, and co-workers over things that has never bothered me before. I never had any side effects with my last birth control."
