"i&#039;ve had implanon now, for almost 5 years. i have gotten it changed out at my 3 year mark. 
the insertion process is similar to an iv getting put in. the second time, piece of cake; a pinch. after the insertion, the first time, it was swollen and sore for 2 weeks, but thats normal, your body needs to get used to it.  second time, it healed in a week. it was inserted in the exact same spot one was taken out from.
since being on this, the first year, periods were sporadic but normal, then they waned off; the last few months before i changed my implant, i had light spotting for a few days and then after i changed it no periods at all. i have had no pregnancies, mood swings or weight gain. no hormonal changes via sex drive or breakouts. i love it."
