I was just wondering... I smell a strong odor of urine in my underwear and have large brown streaks UP towards the front seam of my underwear. My doc says I have an abnormal pap smear and that the huge brown streaks are dried blood. I'm not buying it. It smells just like urine. He's tested my urine (I don't know what for) but he says nothing's wrong with my urine. This brown streak just about covers my underwear from front to back. I can't keep a set of clean underwear because of this. I'm tempted to leave an attachment picture of the brown streaks but maybe it's too graphic.
