"i have had the implanon since december 21, 2009. i am overall satisfied with it except i have had lots of bleeding. i started bleeding from the first day i got it for 5 weeks then had one normal period a month later,  and now i am going on my 5th straight week of bleeding again and had to be put on estrogen to help stop the bleeding.  you wouldn&#039;t think i sound very satisfied but i haven&#039;t had any hormonal, weight or sex drive problems which is my problem with all the other types of birth control.  this is a side effect that they warn you about when you get it, but your body should adjust within the first year so i am waiting it out with my fingers crossed! recommended but be prepared for the possible side effects."
