Whitish discharge after haidh

I am unsure of how to count my period days as, usually, even when I am not bleeding or on my period I have a small amount (the size of a two rand coin approx) slightly yellow/cream colored discharge or perhaps this may even be from sweat as I don't feel it coming out. So, when I count my period days, towards the end of my period about 8 days in, I see this yellow/cream color on my sanitary towel. Would this be considered as the end of my Haidh as it is the normal color that is always on my sanitary liner? Do I make a ghusl when I see this color or do I wait a full ten days. I am unsure as there is never actually no color on my liner, and, all of the masalas that I have read say that you have to wait for your sanitary liner to be completely white,but, I never experience that my sanitary liner is completely white.
