Etonogestrel
"I cannot begin to tell you how much I hate myself for staying on this for as long as I did. I went from having extremely light and short periods to being on it constantly for the past year and a half. The only reason I was using birth control was so I would feel comfortable and protected during sex. But considering I had my period just about everyday, it was useless. I cannot tell you how many pairs of underwear I've ruined or how many boxes of tampons I've gone through. Let's not forget about the dramatic weight gain. In the past year and a half I gained a good 50+ pounds. Yes I know the birth control didn't put the food in my mouth, but my fast metabolism was shot. Even when I went on diets I did nothing but continue to gain weight!"
