Late spotting day period was due!

3 days late had spotting the night my period was due, the next night I spotted again, Thursday night I tested and saw a faint line but it was blue dye, and last night I used first response and can see a line in person but hard to see on pics. Tell me if y’all can see them!!! The inverted first response is two different tests bc I saw the line in person and I wanted to take a second test to be sure, but the second test was super faint I’m wondering if it’s bc I peed back to back and IF I am I would be super early still.
