Etonogestrel
birth control
"I've had Implanon for about a year and a half. I have to say that this is the worst birth control that I have personally used. After reading some reviews below now I know it is in fact the birth control. I have had severe mood swings, I gained 110 pounds in the year I've had it. I've also had hair loss and headaches. This will be coming out within a few weeks, and I can't wait."
