"this november 2015 i will have had implanon for 3 years. the only thing i guess i could say that was bad was that i had a period for maybe most 2 weeks after a year of having it. after that i haven&#039;t had any period since. i get cramps rarely, no spotting. very effective against pregnancy, very effective for stopping implantation if anyone was wondering because i know i was when i got it. i plan to get implanon again when it&#039;s time to remove it. i think i&#039;ve had an overall positive experience and i hope the second time around is good as well!"
