"i was very nervous about trying implanon after reading all the negative reviews, but went ahead with it anyway.  the procedure was quick and practically painless.  the spot was tender for a few days and i did have an ugly bruise and now a tiny scar, but nothing that is too terrible.
i started implanon while i was on my period, which lasted for about 21/2 weeks, give or take.  but the bleeding was minimal and it wasn&#039;t too bad.  then after that period ended, nothing.  i haven&#039;t had a period since i had the device inserted in december of 09.  i haven&#039;t noticed any weight gain or unusual moodiness. this has been the best birth control i&#039;ve ever been on.  my advice, give it a chance.  don&#039;t let the negative reviews scare you away!"
