my daughter who is about 36 weeks pregnant had an ultra sound today. She was measuring small (fundal height). The ultra sound showed the baby is about 6 pounds and fluid level was normal. They sent her home saying everything was fine. Doctor called 2 hours later saying that some texture was detected on the kidneys and the want to do a level 2 ultrasound with a specialist. She has to wait till tomorrow to even get this scheduled and is worried .... what does all this mean?
