birth control
"I had Implanon inserted in March of 2010 and it was fantastic for the first 8 months. However, shortly after October I began my period, and it continued NONSTOP for the following 5 months until I finally caved and had it removed. Both of my college roommates had it, one a whole 3 years before me. My advice would be to see how you react to hormones before you make this commitment. "
