birth control
"I'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'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"
