"i used implanon for 6 year with 2 insertions. it was very effective and i loved not having to worry about birth control for such a long period of time. the only reason i had it removed was because i would have a heavy period for months at a time. i was on my period for more than half the time i had the implanon. when i had it removed, i noticed my face clear up and i lost a small amount of weight. i have a friend who had implanon and she had it removed due to complete lack of periods. she couldn&#039;t stand being irregular. so implanon seems to have a big effect on periods."
