pregnancy test day after ?

so i took a pregnancy test just because and it was negative, looked at it today and had small tiny line where it looked like a line was gonna form. Does that just happen because it sat over night?

It's probably from sitting but is take a pink dye test in a day or two just to make sure. Blue tests are horrible

You aren't supposed to read the test after so many minutes. Especially blue-dyes. They are notorious for evap lines. Retest.

yeah i like pink dyes way better! im actually going to the gyno today so ill just ask for a test!
