So for two days my bladder didnt hurt but i had the feeling i had to go to the bathroom every five minutes. Then the next morning i started peeing blood. It wasnt light either it was heavy and dark blood and i didnt have my period. I went to the drs and they tested it for everything, bladder inflamation, STDs, a UTI and before i got a postive or negative for them they pit me on meds to treat a UTI. It got better but everything came back negative, what did i have or was wrong?
