Faulty test??

Am

I’ve taken a supermarket brand test this evening and as the dye was running through what looked like a line started to show. Now that the test has started to dry I can barely see anything/ it looks like it’s negative. I also dipped a clear and simple in the same urine when I saw a line and don’t think I can see anything on that test. Does this just look faulty- photo taken at 3 minutes
