Is it normal that my urine is leaving behind a white residue?

ok so this might sound weird, but that's why i went to this site. i usually pee in a blue cup, just because our toilet in downstairs and my room is on the second floor, far away, and i have a very small bladder. but anyways, i've noticed recently a white residue that's been at the bottom of the cup, it's sort of... sparkly too? it's very hard to clean off too.(i've peed in a cup for a few years and this has never happened) i do not do drugs, and i don't know what this could be. please comment on what you think might be causing this white residue! thank you

    You probably have an infection. Go see a doctor.

    It could be an infection of some sort or your semen could be reacting to the minerals/chemicals that the cup consists of. I think you should play it safe and go see a doctor.
