Question

I took a first response test which is provided below and it came back with a thick line but faint. I am currently 5 days late. Here is where it gets confusing. I do not know if this is a faint line or if it’s an evaporation line due to the fact it did show once I took it and I thought I seen a line within the time frame and you can see the thickness of it BUT you can now see it darker over time. Going forward today I used my first morning pee for a $1 test and i know I wasn’t seeing things because my husband watched it happen as well. The line was showing at 3 minutes very faint then it completely turned white like the indent line. Has anyone had that happen? What the heck should I do?
