"i first got implanon in july of 2011 and a month later i had my period for about a week, maybe a little longer which was strange for me because it usually only lasts a few days. it was very light though. i did get some acne due to the implanon but after a couple of weeks it went away. i also still get the mood swings, but that could just be me..now its been 2 months and i was scared because i haven&#039;t had my period at all but with reading other reviews i guess its normal. i absolutely love implanon and i recommend it to any girl who is thinking about it!"
