First Response Digital Test Question/Issue

Chelsea

I took a first response digital test this morning. It showed up a clock, ?, yes+ and no- then went to a solid clock and never changed. Did the test just fail or did it detect hormone but not enough?

I also took a 6day sooner normal first response test yesterday and it came out different. Usually it’s bright white when negative and this time I could maybe see a line and it wasn’t bright white. So I am very confused. My period is due tomorrow.
