Evaporation VS faint line

Tabatha • I`m married to my high school sweetheart. We have two beautiful daughters.

On the first response tests, does an evaporation line turn pink? I’ve always heard that an indention line or evaporation line doesn’t get the pink dye in it. I’ve seen a few posts on here though that say they do. I don’t read my tests after 5 minutes, but a few mine the faint line I see on them darkens as they sit. I’m just curious.
