Ethinyl estradiol / norgestrel
"I've been using Cryselle for three months now and it has been amazing!!! I used to get horrible cramps that often made me nauseous and that resulted in me missing several days of school just because of my period. Since I've been on this birth control, my period changed from 5 days to 3 days and I bleed much lighter with mild to no cramps. The first couple weeks I had some mood swings and cravings for food but it stopped after the first month. The only downside to it is it will make you feel nauseous if you take it at night and my breasts are very tender and sore during my period. But other than that A++!!!"
