My doctor did the same thing... however in my case I was lucky he did as the antibiotics did nothing and I ended up in hospital for two days with a kidney infection triggered by the UTI which could have led to pre-term labour I am glad my Dr didnt wait for results... But i do understand why you are upset.... I guess there are two sides to every situation and I was on the other (I also didnt have burning or pain when urinating, no blood in urine etc etc)
