Could it be possible liquids from MY BRAIN are coming out of my nose instead of mucus?

I have been sick now for two months and the only thing i have is mucus. Im constantly blowing my nose everysingle day and the liquid is starting to look really liquidy and barely thick and also they are white instead of greenish like boogers are supposed to be! im so scared bec i have a horriblee migraine by my brain area..so could it be my brain? :(
