"i had the implanon inserted early march of 2010. my son was six weeks old. my arm was only sore for two days and i have no scar now.  i had one period ten days after insertion and no longer have any periods.  i am breastfeeding so i am not sure if my period will come back when i stop.  i love this form of birth control. i would recommend it to people looking for something simple. i know i always forgot the pill and now i don&#039;t have to worry about it. i love this so much."
