Could this be an evap?

Christina • Mother to an angel in heaven. preparing for ttc for baby #1
Took this test the day before yesterday and yesterday I noticed just like the other first response test I posted. The line had gotten darker maybe as soon as I stopped watching it. Could it be positive or just an evap? I've never had evaporation lines with FR before :/
And this test is from just now about 5 minutes ago...
