What Causes Thick, White Discharge After Periods?

I know my normal vaginal discharge cycle, starting clear n thin and abundant during or near ovulation and getting increasingly thicker n slightly white as the month progresses near my period. My period can be random and irregular. However ever since my last period ive had constant thick white discharge, no smells, and it dries flaky white. I did get checked initially and doc stated ph and everything else looks fine microscopicly. But i know my normal cycle, this just doesnt feel normal. any suggestions?
