"i had my first implanon put in at 2009 and am now on my second one and love it! i haven&#039;t had my period since two months after the first one was put in. yes i&#039;ve gained some weight but the cramps and mood swings are gone! i love this method of birth control! i don&#039;t have to use condoms with my partners and i don&#039;t have to worry about getting pregnant. my only small complaint is my arm does get sore around the implant and throbs every once in a while."
