Hi there! Has anyone had a test be negative, just to look at it the next day and see a faint positive? Or, was it an evaluation line?

AF due tomorrow - Christmas Day :) No symptoms, but typically cycle comes 1-2 days early each month. Took First Response yesterday...was negative and took another test last night.

The test last night looked very negative. Looking at the test again, a day later, there is a line, but believe it could be an evaporation line? Don’t mean to sound strange looking at a day old, thrown away test. Just have been trying for a few months and hopeful. Any input appreciated. Merry Christmas and Happy

Holidays to all 💛
