"when i had gotten my first period while on nexplanon it had lasted 2 months. but it was very light so i felt like i could deal with it. after that period was over i made it from october 2014 to july 2015 with no period and no pregnancy scare. since i&#039;ve gotten my period back i have it almost all the time! like bleed for 2 weeks then a 3 day break and my period comes right back. i used to say how much i love it but it is now almost september 2015 so i have been having my period for about 3 months straight and it sucks. i have lost over 15 pounds from exercising since i have had it implanted so i wonder if that has anything to with the almost constant period."
