"i&#039;ve been on nexplanon for 2yrs and 9 months(03/2013). it has been the worst mistake ever. i&#039;ve had sore breasts, bad acne, extremely weight gain, severe headaches, no sex drive, blurred vision, and constantly hungry.  i just had it removed 12/9/15. i couldn&#039;t take any more. when i got it removed i felt something lift up off of me. i feel like a new person. the breast soreness went away instantly. the only thing i see good with it is no periods and i didn&#039;t get pregnant. i didn&#039;t have that many symptoms with the implanon which i had for 3 yrs before getting this one. but to each his own. this is my experience but everybody different."
