positive?

I took this test at first it showed with a less dark but visible second line but not much blue. Can an evap line show up right away? it was more clearish than blue for a while (past the 10 minutes extremely slight blueish tint but looked quite clear. it's about an hour later now and it's more blue now. I really hope it's an evap! Lol any tips? I'm gonna re test Tlmorow just nervous Tia.
