"i had the implanon implanted on february of 2012. the insertion process was pretty painless. only thing that hurt was the numbing shot. after that, i didn&#039;t have a period for about a week, then i got a very light period for nearly 6 months. may sound bad, but it really wasn&#039;t. very light, no cramps or anything with a regular period, only light bleeding. after the 6 months it stopped for a couple months, then was back again for nearly 2 weeks, still very light bleeding. i have had just a few mood swings, but other then that no side effects. i recommend it. it works great."
