what could cause blood to be showing up in urine not from kidneys or bladder
Even if visible blood in urine resolves spontaneously, a thorough evaluation by a urologist is advisable. Blood in urine can occur in women with bladder infection. Blood in urine can also be a symptom of other medical and urological problems such as bladder cancer, kidney or bladder stones and kidney cancer in women. Women who have history of smoking, even if they quit as long as 20 years before are at increased risk for bladder cancer; so are women over age 40.
