"i love nexplanon. i got it in august 2013 when i was 18 and it&#039;s currently september 2014. the week i got it implanted i had my period for a few days and have not had my period since. that&#039;s one year with out periods. it&#039;s fantastic. i haven&#039;t experienced weight gain or moodiness or any other symptoms. i think it&#039;s extremely effective."
