Blue Dye tests? ๐Ÿ˜“

I got two very faint lines on two blue dye tests. Took two red dye tests and didnโ€™t see anything. Is this common? I feel like Iโ€™m still pretty early to test, but my periods are not and have not ever been regular, so Iโ€™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. Iโ€™m so confused & was really hoping that my blue dye tests were accurate ๐Ÿ˜ž
