35w4d and I had to get a ultrasound on my kidneys this morning due to possible kidney stones. The woman who did the ultrasound didn't say anything other than my kidneys aren't draining completely. I know this can be normal during pregnancy because of baby's possible position and pressure. Have any of you ladies dealt with this and didn't have to do anything other than have your baby? I never had this with my first. I really don't want to have to get a stint put in.
