Blue or pink dye ?

So I few days ago I took a pregnancy test faint positive the next day I when back to look at it and clear positive but I know your not supposed to look at them after so long because it can be incorrect

So I waited a few days with a digital and said not pregnant and today I took one again with blue dye because my period is one day late and it a faint positive again

And I also took a pink dye one but it look like the dye didn’t work

So I’m so confused

What should I do keep testing or just stop
