my ultrasound tech asked me to couch, lay on my side, and she giggled baby around a little to get movements from her, baby wouldn't move. Baby has a heartbeat and was moving around fine while I was eating breakfast and also as I was waiting for doctor to come see me. my concern is the reason for why the tech was trying to get baby to move during the exam, she wouldn't answer me and I forgot to ask the doctor since baby was moving around while I waited for doctor to come in. what could have the tech been looking for?
