Hi there. One thing to keep in mind is that you can not read a pregnancy test after the time period stated in the directions. An evaporation line will appear as a second line in most tests and creates a false positive.
I would take a second test with first mornings urine and follow the directions reading the test within the window they indicate. good luck
I just took a test and thought the same thing. I took another test the next morning (first thing) and it was clearly negative... Hope the best for you guys.
