any ultrasound techs on here ???

Z

I have a question about what they found on my ultrasound for my own kidneys not the baby's. she said she found something and asked if I had a UTI recently. I said in January. she asked if I have pain. then told me not too worry too much and that my dr will explain to me. she said it's common when your pregnant. I don't get results for 3 days and I'm just really curious on what this can be. any ideas?
