Implanon

I'm in Australia so not sure what it's called elsewhere but I have the Implanon: Implant in my arm.
I had my fourth baby last year in March 2015 and I've breastfeed him and still do although It's slowed down a lot as I've returned to work.
Two months ago I got my VERY FIRST period since giving birth to him over a year ago. I have had my period the whole time since I got it last time and it's doesn't seem to be going anywhere anytime soon. I only need to use light panty liners and it's not bright red. Any suggestions on what I can do? I'm thinking about having it taken out although don't want another pregnancy at this stage. 
Does anyone else have this problem?
