"i had the implanon put in march of 2009 and had it replaced in march of 2012 because i love it! insertion was a breeze, and with the exception of the anesthetic, virtually painless. i have not had a full period since that first month with only (extremely) light spotting every few months. i have not had any noticable weight gain or mood swings due to the implanon and even less outbreaks of acne since starting it. i would say the only downfall is also a perk, not getting my period. i have worried that i was pregnant, but it was just worry. replacing it was just as effortless as the initial insertion. it can take anywhere from 3-30 min to remove it but it doesn&#039;t hurt. you will feel only a little bit of pressure. mine only took 5 min to remove"
