Ethinyl estradiol / norgestimate
"I took Sprintec for 3 1/2 years consecutively and it prevented pregnancy and cleared up my acne quite a bit.  My period used to be a bit unpredictable since it wasn't on a 28 day cycle.  On Sprintec my period came VERY regularly, practically down to the hour every 28 days and only lasted the regular 5-6 (normal for me). I stopped taking it to get pregnant, which happened 6 weeks after I stopped taking Sprintec and I have a healthy baby girl.  I breastfed for the full first year so I was on the "mini" pill. Last night was my first night back on Sprintec.  I forgot to eat anything with it and woke up at 4 A.M. throwing up.  7 hours later I'm fine and it works great otherwise. Just take it right before or after eating a full meal."
