Im having blood in my urine but no signs of infection and all my tests were normal even a cat scan .. ?

Hematuria: Are you able to see the blood or is it only present under the microscope? Can you be sure it's not from the vaginal area? Have you been evaluated by a urologist? Perhaps a bladder cystoscopic examination would be advisable for thorough evaluation of hematuria. I recommend consulting a urologist if you haven't been seen by one and blood in urine persists.
