Positive maybe?

So I got a faint line on this test but it didn’t show up until all the pink dye was done running, which was about 10 min. I tried doing the water test where you drop water on it and if the line doesn’t go away it’s supposedly a positive, this is the test after I dropped water on it the line never went away. (It dried again that’s why it’s yellow the line was still there when it was wet) Feedback please!!💓
