"i&#039;ve i have this implant for 3 years- just got a new one put in. my period went away for the first about year and a half then became sparatic as all hell- i am married and super sexually active, and have had no pregnancys thanks to this. you don&#039;t have to remember to take a pill, shot or anything- super reliable and low maintenance. the implant was soar about 3 months in but that went away after about a week"
