"insertion left my arm bruised for about a week, nothing terrible. there is a small scar at the insertion site. i&#039;ve had implanon for just over a year now. the first month or so i experienced low libido, but luckily for me that issue went away. i have my period about once every 6-8 weeks, it&#039;s irregular but there is much less blood than before i had it in. sometimes i bleed for only 3-4 days, other times it is 7-8 days, but either way it&#039;s no big deal, and i haven&#039;t experienced any substantial changes in my skin or my weight. i highly recommend trying this method of birth control. nothing works for everybody but if implanon works for you, it&#039;s much more convenient than pills.
