Has this ever happened to anyone else?

Aunt Flo is about 2 days late so I decided to take a test with my first morning urine this morning.

I waited for it to come up with the results and it looked quite clearly negative. Fine, I must just be having a weird cycle for whatever reason.

Then I caught the test at a different angle and I swear there is the faintest line. So faint that my camera isn’t picking anything up but it is there.

Has this happened to anyone else? Is there always a super faint line? Is that just part of the test?

Going to retest in about a week if AF doesn’t turn up
