"i have been on implanon since 2007. at first my left arm where it was inserted had pain for the 1st week but for the whole year it was great. i didn&#039;t experience any of the side effects. now that it is 2010 it is still in my arm, but my menstruation cycles skip a month and then i get it and when i do its heavier. i&#039;m not sure if i gained weight because of this product, but i was naturally always skinny before this product. i exercise and eat normally as i used to so i&#039;m not to sure if it is the implanon implant. 
but i love this birth control very much because it works well as far as not having to worry so much about it, but i have had mood swings especially now for no reason and a little lower sex drive."
