I had an uti last week and treated with cipro for 3 days (2x250mg). symptoms returned mildly and now i have bacteria/blood in the urine but no leucocytes, confirmed by the lab. my period is about to start tomorrow. should i take antibiotics or not?

A three day course of Cipro could be enough for a noncomplicated lower UTI but may be insufficient if you have history of recurrent UTI because bacteria, especially E. Coli, are often resistant to Cipro nowadays. With that urinalysis, you can increase fluid intake for a day or two but if symptoms get worse the next day, you may need antibiotic again, not Cipro, for at least 5 days.
