I Have Been Experiencing A White Cloud Discharge For Over

I have been experiencing a white cloud discharge for over two weeks now and im on the depo shot that i just got today 1-25-16 but it started out as clear color and over a few days it changed to a cloud color then a white and it has not stopped yet it aslo had a orange color on the tissue when using the restroom. Ive never had discharge for this long. Could it be because a hormone imbalace, or could this be some infection that needs medical attention. Needing some oppion please
