Someone tweak for me

Emcee • Married, I`m a Nurse; but a stay-at-home mom for now; 3 kids & trying to conceive my last baby #4
Glow said to take a pregnancy test today. I am 11 DPO and AF is due on Saturday. I usually spot brownish discharge a couple days before AF arrives but I haven't got that nor any PMS symptoms that I usually get before AF comes.... 
I guess AF will be seeing me Saturday 😔
