I took this test this morning when I got home from work, it looked negative when I last looked at it within the first minute or so, so I went to bed. When I got up, about 3 hours later, I looked at it again and this is what it showed. I have read that this particular brand only has a sensitivity of 100 and AF isnt due til Tuesday. So, I need opinions..... is this probably an evap line? I am refusing to think otherwise until I test again in a day or 2 but it is driving me crazy!
