I see something, but of course can't see any color (and am a little wary now of jumping to conculsions until there is a clear result, lol)
It doesn't have to be first morning urine... if you can hold off on drinking and peeing for several hours, you can get concentrated urine anytime (though I think its late there, now, right?)
I vote that you pee in a cup in the morning so you can retest with it if you need to, like if you think you see a line, go buy an FRER and use the same urine, lol.
