Ethinyl estradiol / levonorgestrel
"I was on Levora for a year and absolutely loved it. Never a negative side effect. I'm finishing my second month on Chateal and have gained weight, experienced extreme mood swings. Crying and yelling for no reason. I'm also cramping like crazy before my period. I'm in more pain then before the birth control. (Which was the reason I started in the first place)."
