"i have been on implanon for nearly two and a half years now.  i had been on the depo before that for about five years.  my biggest concern was not getting my period because that was the whole reason i was originally put on birth control.  i essentially cannot function when i get my period and with the implanon i have not gotten it once.  i gained a lot of weight on the depo, but once on implanon i lost 20lbs. although i was exercising regularly as well.  the only negative side effect i&#039;ve experienced is a lowered sex drive.  other than that i love this birth control.  i think people just need to realize that different bodies respond differently to medications."
