Etonogestrel
"This birth control is only good for one thing, and that's keeping me from bearing a child. I've gained 40 lbs, and my skin was perfectly clear until the 6 months of constant spotting were over. This birth control had more cons than pros and I'm over it. I'm getting it removed next month, have the appt and everything. Oral contraceptives have never done me wrong, so I'm going back to those. Do not get this implant."
