Faint positive or evaporation?

[Kel33]

Good morning!
I don't know if I'm seeing a faint positive, evaporation line or just seeing things 🫣

I can see a shadow but not sure what it is tbh, I'd do a 4 hour hold with not much to drink and do another 🤞

That's what I feel like... There is a shadow but who knows 🫣
