Any idea? Faint line pls read

So I took this pregnancy test on the day of my missed period. It came up within 1 minute very faded but visable but within 4 hours It got so faint that my partner couldn’t see it but I just could. Anyway I’ve bled since then with clots ect. But this is what the test looks like 5 days later?? I took 2 other tests too confirm and they both had faint positives so I assume I was pregnant, and I bled heavily with clots and tissue so I can only assume I misscarried. (Which i understand with the stress I was under) but I’m confused. With this test looking like this 5 DAYS LATER.
