"i&#039;ve had the nexplanon for a year and 2 months and i&#039;m 18 and i haven&#039;t had a period since i been one it i&#039;ve gained about 50lbs since i&#039;ve been one it and i been doing everything i can to lose it and it won&#039;t happen i&#039;m getting it removed next month but i really don&#039;t recommend this. i&#039;ve had the depo and it messed up my back and still didn&#039;t have a period on that but i thought about the implant and it does work not getting you pregnant.  but i&#039;m gaining so much weight and i do everything and still gain it. please girls if you don&#039;t want to be big and have no period, depression have bad anxiety, be tired 24/7 don&#039;t get it or the depo. it sucks.  my boyfriend wants me to get it removed because i keep gaining weight before i was on it i was 145 now i&#039;m 195"
