2WW and CM progression?

Strange question but did anyone who got a BFP notice their CM almost dry up before AF was due? I’m 8DPO and usually by now I’d have thick creamy discharge but I’ve had hardly anything, a little tiny bit of green creamy like snot (barely anything) and just feel generally dry. This is unusual for me...I know CM isn’t an indicator of pregnancy either but feeling hopefully as something feels different
