Ethinyl estradiol / norethindrone
"I did not like Generess.  It made my periods very regular (but heavy) and did prevent pregnancy well, but it made me breakout like crazy and gain weight.  I've never had a real acne problem until I got on this pill at 20.  I've been on it for 4 months and have has non-stop cystic acne.  This acne has been not only on my face, but also on my neck, chest, back, and butt.  This pill also made me gain 8 lbs, and I have not changed eating habits at all.  This pill has also caused me to have ridiculous mood swings and be a cranky, moody, slightly bitchy person.  Would not recommend"
