Repeat anatomy

First time mommy here so everything makes me nervous! Has anyone had to repeat their anatomy ultrasound simply because their little one wouldn’t stretch out their legs?? I really hope I’m just being my anxious self but I can’t help but feel worried something is wrong that they’re making me come back for a repeat anatomy simply because they couldn’t get my little to stretch out her legs for one of the pictures that they needed. Surely they would have said something if they thought anything was wrong right?
