Ethinyl estradiol / norgestimate
"I just started taking the pill and 2 and a half weeks in my period started.  It was reg/light flow but the cramps are horrible. I've never had cramps like that and it lasted for six days straight not to mention I'm going on 10 days still bleeding a regular flow and it doesn't look to lighten up anytime soon. I thought it would lighten and shorten periods but I'm having an opposite reaction."
