Okay, i just got tested today for a white sediment in my urine. The urinalysis test came up negative for a UTI, and the doctor said it was unlikely i have a kidney stone. I just recently got a new girlfriend with whom I have had unprotected sex as she is on the pill. I really like her, and if I test positive I am positive that she is the reason for the STD (last sex was a year ago and I have been tested since). How do I bring this up, as I still really like her and do not want this to disrupt things as long as she gets treated?
