Faint line/ less line

Sam

Hi, I took a test 3 day before I was due which had a faint line ( first pic) wasn’t first urine of the day, Took another today 1 day before period ( 2nd pic) the line is barely visible, lighter than the one before. This was the first urine of the day. I’m worried as I’ve had chemical pregnancy’s before . I know I should just wait till I’m due or couple of days after but I have to change what I do at work if I am pregnant so needed to know quickly.
