Okay, I have had 3 bladder infections in the past year and a half. So when I felt like I was getting another one at the beginning of the week, I went to the infirmary here at my college. The quick urine dip showed positive for blood, so the sample was sent to the hospital to get checked under a microscope. It came back as positive for blood, but no signs of infection. The doctor at the infirmary seemed a little concerned and confused. I am supposed to go back on monday to get another test done. I'm a little freaked out! It is not enough blood that I can see it when I pee... Does anyone know what could cause this? Because i'm going to worry til I know whats wrong. Any opion would be appreciated!
