"so there&#039;s many opinions out there about the nexplanon/implanon. when reading everything, always know that all birth control affects everyone very differently- not 1 person will be affected the same way. i had the implant placed february 2014 and got it removed july 2015- a year and a half. i loved it- at first, i had regular periods and then about 4 months in they would come every now and then but be very light so it was not a problem. at about a year, i stopped having periods altogether... but i also lost my sex drive completely. being married, it is a very big issue to not have a sex drive. i did gain a little bit of weight, but nothing too crazy. i got it removed before the 3 year mark mainly because of my loss of sex drive."
