Boots early pregnancy tests

I’ve been TTC for 8 months and this morning at 5:10 i took a pregnancy a Boots early pregnancy test. I checked after 3 mins but hadn’t turned light on and basically used the moonlight but didn’t see a second line. I then checked test at 8am when I woke up properly and saw a faint second line. Has anyone had evap lines with these tests?

I will take another test tomorrow morning but it’s been on my mind all day 😫 my period is due Wednesday.
