Ethinyl estradiol / norethindrone
"I've been on this for about 6 months and have had a very positive experience, except when I started taking it my bleeding continued for about a month. I had some mild cramping, which I didn't even have to take Advil for. I got on this pill for endometriosis, usually I have debilitating cramps and severe proctalgia fugax during my period and not have experienced any of that. My only symptoms are breast tenderness for about the first month and I've gained a couple of pounds at the most. No acne. Highly recommend!"
