"i got nexplanon in on september 1st. i was on my period when i got it it is now december 1st and i&#039;ve still been bleeding very heavily. i guess the birth control is working because i can&#039;t have sex to get pregnant because of the period. a plus is that i don&#039;t have to take a pill everyday or get something implanted in my vagina... but i hope i get off my period soon giving it another month"
