How long does it take for a test to be negative after CP?

I found out Sunday night that I was pregnant after being 3 days late, I took two tests and they were faint but the lines were obviously there. So Monday morning I went and bought 3 more tests so I could be sure and those were also faint but definitely positive, Monday night I started spotting. It was light pink and very light, Tuesday morning I woke up and it was a lot heavier and darker so that afternoon I bought two more tests and they were positive but the line was so faint you really cant even see it in the picture. I was still hopeful and thinking that maybe the bleeding would stop and the next test I took would be positive, bleeding didn’t stop. I took another test yesterday morning as soon as I woke up and I felt like I could see a line but my eyes could’ve been playing tricks, even if the line was there it was way lighter than the day before. And just now I took another and it looks completely negative to me, I’m gonna take another in the morning just to be sure but is it possible to already have a negative this soon after CP? I keep thinking that maybe the first ones were false positive but I feel like it would be impossible to have that many in a row and I was also feeling symptoms, and also could I have seen it pass? Ive been having tiny dark red clots but Tuesday I had a bigger one that was more like a cloudy clear with tiny red specks in it, could that have been it? Pictures are in the order I took them
