ok, maybe. Last Thursday I woke up and had lots of blood in my urine. This went on all day everytime I peed. I thought I had a kidney stone. Then it stopped on Friday and not again until Sunday and I have been doing this ever since. I went to the dr and they did an IVP which showed no kidney stones, kidneys are good in location, contour, and such...So I have an appointment this Friday with a Urologist. What do you think it might be?
