I think I may have had a chemical... line and then no line?

I took the first (top) test six days after my missed period since I hadn’t realized I had missed it yet and I think I got a faint line, then I took a second test this morning and didn’t get any line. I started passing large clots and dark blood yesterday. Does anyone else see a faint line on just the top test?

Edit: photos of both tests were taken at the 2-3 minute mark when the box said I should look at them.
