I've only had the Implanon for what'll be two months March 8th. I had it inserted January 8th, started my period February 15th and have been on it since making this day 18 of my period (March 4th). I have plans to have sex next weekend and would really want to know how long this will last or if there's a way to shorten my period. I also would like to know if certain side effects will go away. I've gained weight, my face is breaking out, my sex drive has increased, and I've become very moody.
