"i have had the implant since april 2010, now october 2011 and at first, it was great! experienced an 11 day period (usually never lasted more than 5 days) and that was about it. the insertion was about 2 minutes and the only pain i experienced was the numbing which lasted a couple of seconds. i didn&#039;t have my period for about 6 months which was cool, never got pregnant or had any side effects. my concern really is that now, or recently i&#039;ve been having my period non stop. i&#039;m currently on my period, for the 8th time in 2 months. they&#039;ve been heavy periods and the cramping sucks. i&#039;ve been breaking out really bad and experiencing very bad mood swings. i become very sensitive and impatient. it&#039;s a great birth control but i&#039;m at a loss for words lately."
