Im confused

I'm 4 days late....I took a test the day before AF was due and it was negative. I have PCOS and sometimes AF is not regular so that mixed with the heavy heavy stress I'm under I haven't gave me being "late" to much thought, but I'm just confused because 3 days before AF was due all the way till today (4 days late) I started getting ew(eggwhite) discharge like you get while ovulating!! And its a lot!! What in the world is going on.....Has anyone had this before? Is this normal?

***I'm not concerned about being pregnant or not my concern is about the discharge!!
