Ethinyl estradiol / norethindrone
"Continued: I experienced some breast tenderness and slight breast growth (I ain't complaining about that) I'm currently in my second pack and experiencing no side effects at all! I am very happy with this medication and impressed with how well it worked out for me despite all the negative reviews. Don't let the reviews frighten you, everyone's BODY'S are different so try it out for yourself!! :) good luck"
