Faint lines?

So I have been going through so many symptoms and honestly I took a test on Saturday to Just see if I could be and boom! There was a line within the two minute mark. Then today I took another one and there was also a faint line in the two minute mark too. So I really need your help to see if you see it too. I am doing blood work today just to clarify!

Top test was taken on Saturday

Bottom was done this morning

Both tests were taken with FMU

Also does anyone see the lines getting darker? Idk I feel like I see the one I took today darker than the first.
