Someone please help!

I have been having uti symptoms for over 2 months now with no uti. Docs cannot find any signs of infection, but they do say my red blood cell count is high. This last week i have had 3 urine tests and they all show crystals in my urine. They said possible kidney stone. My issue is, i had a CT scan with contrast in the beginning of the month that showed NO stones. Every thing looked normal. The doc on the phone said that the scan would have seen it if it was there. I am waiting to see the gynecologist this thursday and I'm freaking out! Im a 32 year old single mother, and never had any issues like this till around xmas when this all started. I never had any kidney pain. Its all in my pelvis and burns when i pee. Anyone have a ct scan miss a stone? Also no matter how much water i dribk, my urine is bright yellow and smells strong (not foul)

I assume they did a culture on the urine, CBC, and creatinine. Sometimes a random urine won't find an infection, though there still could be one.

Other consult you may want to consider are nephrologist perhaps a urologist
