Ethinyl estradiol / norethindrone
"I'm 26, first birth control pills I've ever used. I'm on my fourth month, getting close to starting the fifth pack. Pros thus far: no breast tenderness (they did increase in size), no acne (skin actually cleared up), no weight gain (I'm very active to begin with), no nausea or headaches, much lighter periods (prior to the pill, my periods were heavy enough where both a pad and a tampon were needed... Now a tampon alone is good enough!)
Cons: ever since starting it, I've been having two periods a month.. 15 day cycle and it's about two days longer than period prior to taking this pill. The pros definitely outweigh the con, but I can't stand having two periods a month!"
