hi there, you do seem to be suffering from UTI and it doesn't seem to be mild. You may also be having urethritis
along with cystitis
which explains the blood and continous urge to urinate. You should get a routine exam of the blood done and a culture and sentivity as well so that appropriate antibiotics according to the senstivity of the organism can be initiated. Do not neglect it and do visit your local doctor as soon as possible.In the meanwhile drink plenty of fluids and take rest. Take care.
