36weeks Ultrasound turned by world upside down:(

I was 36weeks on Friday and doctor sent us to check the position n measurements of the baby. First I had student tech, she was telling us about stomach bubble n how they check if baby s drinking and peeing the amniotic fluid properly. Then she said she will check with her teacher, then her teacher came. They were talking about the stomach n her teacher was like "no I think it's there". Anyways we asked if everything was okey and they said radiologist has to check! then they both went to the radiologist to show the results. Student tech came back after 20mins, she said radiologist is happy about the results and u can go. We asked if stomach was okey and she said ur doctor will contact you if there is anything. Now I'm super worried! I gotta wait til Monday to find out what's wrong. My heart hurts, knowing that my baby may not be fine in there. I don't even know what was wrong or what their suspicion was.
