I just started a new BC March of this year. It is called Implanon. It is a little rod that is inserted in your arm and it last up to three years. Since I have been on it I haven't had many side effects. The only thing that changed in my body was the fact I haven't had a period since it was inserted :D. The down side to that is that I have gained 13 pounds since March :rolleyes:. Has anyone ever used this form of BC? If so what is your experience with it?
