Alright please help me

I should be around 8 dpo. I tested first things this morning with a frer and it was negative. I am also struggling with a uti so I took a blue dye test because someone said to. Idk I’m just following. Well the blue dye test is the equate brand that everyone hates but I followed the directions perfectly and I really want to know if you think it’s a false positive or not. It came up within two minutes but has not grown any darker since. The test is in the comments it won’t let me hit the camera button from here
