I've been seeing whitish particle/discharge in my urine. WHat could it be and should i be concerned about it? my urine has the normal clear color. sometimes very clear when i drink plenty of water. i have no symptoms of UTI like burning sensation, frequent urination, etc. I don't have vaginal discharge. the white stuff also looks like mucus. i see one or two of them everytime i urinate. COuld it really be mucus? Or semen from sex? how could this stuff get into my bladder? could it be from food i ate? protein? I'm worried. thanks for your help.
