"i have had implanon for about a year now and at first yes, my body did have to get used to all the hormones. at first i was a little tired and cranky. but as time passed my body seemed to adjust. i spot every once in a while but its not bad with a panty liner. i also have not gained any weight with good eating habits and a little workout i am healthy and have lost ten pounds since being on the birth control. i agree it does make you a little cranky but that comes with all hormones. i agree with most others when i say implanon was the right decision for me. but hey everyone&#039;s body reacts differently."
