Blood in urine - what could it be?

[Asparagus78]

My doctor informed me that she was able to detect blood in my urine test. She first assumed it was due to an UTI, but couldn't find white blood cells or any other indicators of an active infection. She told me to come back in for another test in 2 weeks (at my next prenatal check). I don't have any UTI symptoms, and I feel great. What else could this mean?

Thanks mamas!

Kidney stone? Sometimes they are small and you don't even know you've passed one but it causes microscopic bleeding.
