I have had blood in my urine for weeks. sometimes it is visible in the toilet and tissue and sometimes it isnt. i am not on my period. my urine culture came back negative for an infection. i do not have pain anywhere. 2+ ua result?

Blood in urine can be a result of bladder wall injury or growth, or kidney damage. See your Dr for follow up from the UA. They will probably refer you to a nephrologist and do more in depth testing.

I agree with Dr. K' s advice, but in this scenario I prefer a urologist to direct the workup as a cystoscopy may be eventually advised and delay will be avoided.
