It's over

So I took a test September 5th blazing positive, took a test September 6th blazing positive, went for blood work yesterday positive and then last night I started bleeding and now my test is super super faint. Mind you it was not fmu and I drank Gatorade to have to pee but it's almost not noticeable at all but my other two tests that I have taken were in the afternoon as well but with 6-7 hour holds and not just 3 hours. It's been about half a regular tampons worth of blood in the past 4 hours.
