Advice From Implant Users!

Lauren
I got the birth control implant, Implanon, in November. The doctor told me to give it 3 months and then my period should lighten and/or stop. My period has lightened, but it seems to never stop. I have what seems to be a light period for almost 2 weeks, then heavy spotting in between "periods".
I'm curious as to if anyone else has experienced this, and what they have done.
