Blue Dye tests? 😓

I got two very faint lines on two blue dye tests. Took two red dye tests and didn’t see anything. Is this common? I feel like I’m still pretty early to test, but my periods are not and have not ever been regular, so I’m not 100% sure on ovulation, but I think it was Saturday, 8/17. My uterus was very low, clear egg white CM and very bloated/crampy. My last period was July 3rd. Ugh. I’m so confused & was really hoping that my blue dye tests were accurate 😞
