Microhematuria : Small amounts of blood in the urine can be from problems with the kidney (not seen on ultrasound), the tubing from the kidney to the bladder, the bladder, fever or excessive exercise. Sometimes the menstrual flow gets into urine. A normal cystoscopy helps rule out bladder diseases. There are several layers of further testing that can be possible, but to answer your concern more details are needed
