Af 8 days late

AF is very late now, still getting bfns and even a bfn blood test on the 26th. Been having tons of watery cm and my cervix is high, soft and closed.. Last night when I checked my cm was thick, white and gluey... I'm wondering if AF is late because I ovulated late and am pregnant or if I just have something wrong with me... Anyone have this happen and end up actually being pregnant?
