Tests are invalid after a certain amount of minutes. Clear blue can be quite notorious for evap lines, but I'd retest today or for a more accurate result retest tomorrow using the first morning urine 🙂
Evap
I thought mine was an Evaporation line as nothing appeared when doing it but was there about half hour after testing. Turns out it wasn't an evaporation line. I would just test in a couple of days and watch it
Tough to tell as it does have some colouring to it. Technically of course meant to be read within the timeframe but generally tests that are negative stay fairly blank in my experience. Though this particular test is known for evap lines. Obviously will have to test again and maybe go with a digital. If you need to pee during the night and feel this is more concentrated, you can always capture in a cup and then dip the test a few hours later so you can read it in the timeframe. Definitely wouldn’t rule out being pregnant though.
I would do another one as it’s been a while so it not going to be valid one anymore
