"it has done its job, i am not pregnant. i have had it since jan of 2012 and my periods have been sporadic. the first year i spotted once every few months. now into my second year of having it the spotting/light period will last months at a time. i have been bleeding with no breaks since may. after my concern with the thought of having to go back to the dreaded routine of trying to remember taking a daily birth control pill wore off, i remembered the reason why i got the implanon. to enjoy intimacy with my boyfriend without pregnancy. this doesn&#039;t happen with me bleeding more days out of the year than i am not. the only complaint that i have is the spotting; i&#039;ve had no weight gain, no increase in acne, no mood swings, etc."
