"hi i have had the nexplanon for about 3 years now and i must say i&#039;m impressed . i had horrendous bleeding before i got on any kind of birth control and the nexplanon helped control and maintain a normal ish period cycle . i am not pregnant . although i have sex with my bf frequently but i admit i have lost most of my sex drive . i really thought this was a nifty bc because it lasts for years with no worry of replacement or missing a dose , however my depression worsened and i developed anxiety problems in the time i have been on it . although i had bad periods before i started the bc i found that in the second year towards the end , that my periods were back but only lasting 1 to 2 weeks with 3 weeks in between with heavy dark blood ."
