Evap line?

[l2001xx]

So AF is due in 2 days.
I decided to test before.
The 1st test was taken 3 days ago, the 2nd one was the day after the first one and i used FMU.
The last test was taken just recently about an hour ago.
So everytime i took all three tests, a faint line appeared within the time frame (3 min)
But after an hour or so it turned darker and thinner, and it looks like evaps.
Clearblue tests are all I have rn, this never happened to me before :/
Have any of you had a similar experience and actually turned out to be pregnant in the end?

I'd say that's a positive.

If a faint line appeared within the time, that’s a positive test. As it’s happened 3 times, I’d say you can take them as a positive result. Evap lines are more where no line appears in the 3 min window, and then you see a line after an hour or so

They're positive, hun :) congratulations!
