Suggest Remedies To Stop My Period In Spite Of Being On Implanon

Hi, I have had the implanon contraceptive since 2008 and it has been very effective up to now. Im meant to get it out this year, but I am living in South Africa and there are no facilities that recognise the implanon. After not having a period since nov 2008, I have now had my period sine feb 15th 2011. Is there anyway I can stop this, even if its just for a week while im on the implanon?
