Implanon
"I had the implanon inserted Dec '09 and haven't had any problems with it so far. When I got my first cycle after having it inserted, it lasted like two days and I spotted for about a week and a half following that. I've had no weight gain, crazy mood swings or changes to my sex drive, so the spotting is my only complaint. Otherwise it's been great and it's nice not having to worry about taking a pill everyday."
