"i&#039;ve had implanon since february of 2009. i just made my appointment the other day to have it removed this february (2012). i can&#039;t believe its been 3 years already. i haven&#039;t had any problems with it at all. no mood swings and no weight gain. i didn&#039;t read the reviews before i got it. it didn&#039;t hurt, i don&#039;t have a scar. my arm was only sore for a couple of days, but that was minor. all in all it was a great experience. i look forward to getting another one implanted upon its removal."
