Evap or faint lines?

Erin • Muggle Born but very capable in Magic all the same. 1 child. Red hair. Also magic.
On a whim I peed on a stick. Or rather into a cup. On my test I have what looks like an evap line but it showed within two minutes. Can you have an evap that early? I know what evaporation means and realize the test is still saturated but the line isn't colored? Not sure you can even see it in the photo but it's definitely there irl.
