"i have had my implanon since december 2009. i also haven&#039;t had my period since december 2009. i love the implanon though. it&#039;s very convenient, hassle and worry free! no trying to remember to take a pill every day...only downfall i&#039;ve had is that i get cramps when i&#039;m supposed to get my period but it never comes. just spotting like once or twice. overall, i love it and will continue to use this method of birth control."
