13 DPO VVF blue dye tests BFN First Response?

I took the first test and saw a vvfl on 11dpo, then 12 took another , they look almost identical in person. It didn’t get too much darker just a tiny bit. So today 13 DPO I take a First Response and it’s negative 🤦🏼‍♀️🤷🏼‍♀️

Thoughts 💭 do the blue dye ones do this allot? I’m 13dpo so I feel like this month I’m out, and that’s okay but wow my emotions to go from so happy to sad was intense 😢🥺

I added the pics below the first response with the red dye is 13 PDO
