Etonogestrel
"I've had my implant since March '16. Ever since I've had it, I've experienced severe headaches that happen at least once every week. I haven't had my period since I've been on it which worries me because I don't know whether that's bad or good. I have gained weight. I use to always stay around 130-140 for about 4 years and now I'm at 170. Other than that, I have no cramps so this thing is an ok for me."
