Anyone?????

I’m over a week late on my period. Had multiple (5 to be exact) faint but obvious positives both on FRER and generic clear blue.. called the doctor, had blood work done which came back at <2 HCG and a progesterone level of 5.72- so blood work is not showing pregnancy. My cm has been white and creamy but I’ve also been getting white stretchy cm that’s almost like my fertile time. Just went to the bathroom and got this... stretchy but almost looks like old blood mixed in?! Is this just the start of AF?! I’m so confused.
