Etonogestrel
"I had this implanted in February of 2015. It's now August, and I've had nothing but great result. No weight gain, only loss. No breakouts, only skin clearing. I think often people blame this own behaviors on their birth control. If you take good care of yourself, eat, well, & continue to work out, I wouldn't say from my experience that you have any trouble. It has migrated up my arm a little bit, but it's no problem. I haven't had my period since March! No pain, or anything bad. I really enjoy this form of birth control. I recommend giving it a go if you insurance will cover it."
