Ethinyl estradiol / norethindrone
"My doctor put me on this medicine for dysmenorrhea. I LOVE this birth control pill. I have NEVER had any bad side effects from it, no acne, no mood swings. I only have light bleeding/no bleeding and cramping when I do have my periods, which only last 2-4 days. But the best part, NO WEIGHT GAIN. I have actually lost 30lbs since I have been on it. I really love this pill and would not go to any other birth control pill."
