Chemical? Diluted pee? False?

1st picture I took at 11:30am and the second was abt a hour later when I went to get more. The last one was around 7:30pm. This wasn't planned at all, I already have 2 littles and my IUD broke and I was going to get my copper iud. I went through a chemical before many times but never had this in the same day, it was always within a week long of testing. Im only about 2-3 days away from what would/could be my period.
