Is this an evaporation line?

[TulipVictory]

Hi I just wanted to know your thoughts on whether this was actually an evaporation line? It has colour but it is much thinner and just to the side compared to the control.

This was taken the day AF was due and I took it as a positive, however, I started bleeding heavy four days later. I had been quite upset as I thought I was pregnant and then I thought I had a chemical pregnancy but I am wondering whether this was an evaporation line after all? Saying that I'm never normally late for AF.

Anyone ?

I’m not familiar with that brand but it’s darker (& a bit thicker) at the bottom than the top so it’s a bit odd.
However, if it came up like that in the time stated to read the test by, I too would have assumed positive.
Sorry op
