Ok so I’m 10 months pp and had unprotected sex a little over a week ago. I got a very strong positive test at 10 DPO with my first, and on a whim after feeling run down, nauseous and cramping when I nursed my daughter, I took a test this morning. I figured it would be negative, looked at it after a few min, thought I might have seen a faint line, chalked it up to my imagination and then threw it away. I just went to empty the trash and it looks like THIS. I know you’re not supposed to read the test after the time frame, but I’ve taken these before and never had evap lines, they’ve stayed totally blank for DAYS when negative. Help?? Why aren’t you supposed to read them past time?
