Are you sure it is your urine,because if you urinate and wipe yourself properly there should be no urine to turn anything brown,but are you aware that your vagina is like a open sore and weeps all the time,so are you sure it is urine,and if there was no vasinal leakage why would we need panty liners HUH,you can also start to drink more water to help with the urine discoloration.....good luck
