I know I know another blue dye test

I got three blue dye tests that were faint like this over the span of a couple days( ofc they are dry by now) all of them looked like that In the time frame they were suppose to be looked at. What are the odds that all the tests I took are false positives ? I’m currently 11 dpo having some brown spotting .probably just going crazy at this point 👌🏼
