Hi there, I have a UTI, I was on cipro for 5 days with no improvement , went back to the doc and the did a culture, at that time my urine tested positive for a UTI...I have been on macrobid now for 3 days... They called me today to tell me to stop taking it cause the culture had no growth.... But I still have pressure and am urinating frequently, no burning , just a lot of pressure and my ovaries actually hurt .... My question is, could this be something worse or is it still possible this is just a bad UTI and I need to keep taking the antibiotics....also did it show no bacteria because I was already taking cipro before the culture was done??
