AF 9 Days late but BFN? :(

[Dottiee]

I have been TTC for 3 cycles, all with my cycles not lasting more than 28-29 days with no spotting. This cycle I had 4-5 days of spotting around when I should have ovulated. I am now 9 days late.. Tested once on my first day late and once on the 6th day, both of which were BFN.

My question is.. Could there be some strange reason for me not to have enough hormone in my urine to show a positive, or was that spotting a super early AF? Has anyone been in this situation before and what was the outcome?

Baby dust to all!
