5 days late and nothing but BFN

So, my periods are very regular, I am currently 5 days late and have tested every day past my expected AF due date and still nothing ( not even a faint line). Ive tried both digital and dye tests. My last pregnancy (ended to ectopic) I was 4 days late and tested positive at this point already. Whats the latest that anyone here has finally tested positive? Feel like AF will show her ugly face but Im hoping she stays away :)
