"my family has a negative history with birth control (mother, aunt, cousin and sister all tried and couldn&#039;t stay on it) however my periods were always extremely rough so at the advice of my doctor i got implanon to help balance the hormones in may 2013. so far so very good. i have had one 8 day period since then followed two months later by a 4 day period. both were extremely light and my symptoms were either dulled considerably or nonexistent. it was incredible!  sex drive did not change at all and i had no problems losing weight on it. i&#039;ve gone from a size 10 to a size 6 with healthy eating and exercise. at times i feel some water retention but that typically happens around the time i would have started my period."
