I Have Opaque White Discharge That Look Like Scrapped Skin.

I have opaque white discharge that look like scrapped skin. The texture was soft and wet. It was about the with and size of a 1/2 dollar. I do not have any itching or burning, neither do I have any signs of yeast. Aside from this white skin like discharge, my inside vagina is clear. I am due for my menstrual in 7 days. What could this white skin looking discharge be?
