Ethinyl estradiol / norethindrone
"Overall, I like this pill. It took a few months for my body to get used to it. The first 3-4 months I had random spotting and a period right in the middle of the pack. I did gain about 10 lbs but i also haven't been eating as well or running as much so that is to be expected.  My breasts were tender for a few months but that's gone away recently.  And my periods/cramps have gone from unbearable to almost nonexistent.. so much better. The only major, major side effect I've seen is my sex drive go way down and some mood swings. But I would rather have these effects than an unwanted pregnancy.  Give it a shot for at least 3 months before you give up on this, ladies!  It will get better and be worth it in the end."
