Evap line or faint positive on Tesco blue dye??

[Ink23]

Took this 6 days before due period because just feeling different. I felt as though I was getting my period roughly 11 days before it’s due, which doesn’t normally happen. This blue line didn’t come up immediately but would say very faint within the 10 minutes and got darker as time went on. What you all think?

I would say you need to take another

Looks positive to me

Thank you. I’ll test again, just been reading a lot about coloured evap lines on blue dye tests being very common 😏
