Kinda confused?

I’m thinking maybe the other test was a evap, but it was so dark, and had color to it so I just thought it signified as positive, I had looked at it at like the 7mm, and it is now like 4 days old at this point, here’s a photo of it the day I took it

And now I’ve took another one to see how darker it got but there’s nothing😩 here’s the side by side of the two. Do you think my first one was just a evap?
