Hi guys, I got the implanon on July 29,2014 and had it removed on September 11,2014. It was  horrible mood swings everything. I gained about 25lbs in that time frame, as well as bad headaches, always on my period and spotting and horrible mood swings. Anyway, today is the 14 of September and I believe I already started a full period. I was wondering how long does it stay in your system (the hormones)? I would like myself back to normal ASAP.
