birth control
"I have had implanon in for two years. It has been an amazing "birth control". I do not take very many precautions and I have never had a pregnancy scare. I did not gain weight while being on this, I actually lost weight. The only negative effect this has had on me is my menstrual cycle. I am constantly on my period (spotting). I go several months spotting with an occasional couple days off. I absolutely hate this effect the implanon has on me, but it may work out better for others. Most definitely most effective as far as birth control."
