birth control
"I've had Implanon for the full three years. I am scheduled to have it replaced in a couple of weeks. I've had no problems with it. Compared to previous attempts at birth control my temperament and mood swings have leveled out. My sex drive comes and goes. My weight went up 30lbs and now I'm back down to my original weight. I had sporadic periods for the first couple of months, light and short, then I didn't have another one for two years. About 6-8 months before it was time to replace it I started having regular monthly periods again. They were light and short still but on a regular monthly basis.  The only complaint I have had with it is that the implant "pokes" at the skin sometimes and makes it itch, but nothing worse or longer than a mosquito bite."
