Evaporation line or not?

[TwoRdue]

I did not know about evaporation lines until after my test today.. im 12dpo and did a test but looked at it for less than a min and saw no positive but when I went back about an hour later this is what I saw... (I did two more later in the day with a negative)

Try a pink dye test as blue ones are more likely to have evaps x

Definitely an Evap line... Those things are evil.
