Ethinyl estradiol / norethindrone
"I just finished my first pack and haven't had many side effects. I was very worried about nausea but if you take it with food you won't have any problems. I have experienced breast tenderness, bloating, water retention (this is where the weight gain comes from), and a little bit of lack of sex drive. I do like it because it has cleared up some of my acne and I believe that I just got my "period" this week which was very light spotting. My insurance covers it also so it's free for me. I'm pretty happy with it so far and I'm glad its reacting fairly well with my body. Good luck!"
