I've had some pretty unclear hpt's recently. I see a line but then I'm not sure so I leave it and when I come back to it dry there's a darker line. Do you think it counts as an evap if it's just a darker line than before? Again, the line is barely noticeable but just gets darker as it dries.. Its happened on 3 different brands of tests. And dont bother with the "dont read tests when they dry" because everyone says that 😂 I'm just trying to see if any of you have had tests like that and they turned out positive.
