Sperm check?? Help!! Please....

We bought a sperm check kit for at home yes I know it said to wait two days since the last time you went but he wanted to test so we did it tonight.. I wanted the 7 min like it said and didn’t see anything.. he looked at it at 10-15 min mark and seen a line.. so is it positive or not?? Or is it there in the first picture and I just don’t see it?
