Hello ladies!

I took a Urine PT a few minutes ago, and after 3 minutes the line for the control was very faint. 8 minutes later, i checked it again and it got darker plus there’s a faint line of the T part. I thought I was just seeing it because I want it to be positive, but I asked my husband to check and he sees it too. What does this mean?

Not sure if the picture is gonna be viewable when i post it but let me know if it isn’t. Idk whats wrong with my app that i can’t post the pictures properly.
