"i used to take the pill (microgynon) but the side effects and my constant forgetting to take it led me to the implanon in september 2009. unfortunately i am not one of the lucky ones who has no periods, instead i get very light periods (sometimes barely noticeable!) every 2-3 months or so for about 2-3 weeks. i have had no side effects, and no longer suffer from bouts of irrational emotion or period pain. 

even if i did experience these side effects i would still continue using implanon, purely for peace of mind, as it is the most effective form of contraception."
