I was diagnosed with UTI last month. I was prescribed antibiotics for three days. A few days back, when I urinated, my urine was brownish (a sign of blood), and slight burning sensation on that same day which was not there till then. I bought some UTI test strips, and my first test was positive for a trace of leukocytes but negative for nitrite. I started drinking lots of cranberry juice and water. I took another UTI test strip yesterday morning, and the leukocytes and nitrite results are positive. I would like to get some medical advice if I should go back to the doctor or wait as I am not feeling any symptoms, but the test results are concerning since I just had one almost two weeks ago. Kindly help.
