Ethinyl estradiol / levonorgestrel
"I was previously on lutera and best pill ever with no side effects until the manufacturer change. So my obgyn switched me to sronyx because she said it's the same equivalent. This pill is TERRIBLE!!!! For the first 3 months everything seemed fine and no side effects. After that I started getting bad headaches 3-4 times a week, I was moody and snappy half the month from PMS time to the end of my period, I got my period before I made it to the placebo pills, got horrible cramps which I never get, crying spells, nausea after eating and breakouts. The only benefits are weight loss and increased sex drive, which my boyfriend loves. My obgyn said if this pill didn't work out she would switch me to lessina or alesse and I am switching."
