Evaporation Line or a Positive

Hi ladies,

I took a test earlier in the afternoon, and accidentally got pee on the indication window I had always been told that would make the test invalid so I just casually tossed it in the toilet bin and left it as a false take. Well I went to the bathroom not long ago now and happened to look over and notice that the test said positive! Could it be a real positive or is it just an evaporation line?! I plan on retaking a test tomorrow when I’m able to run to the store for more but wanted some opinions!
