10 week fetal movement

Is all baby’s movement different at this stage? Our baby was definitely moving and waving it’s arms today on the ultrasound but it was minimal. I just saw someone else post and their baby was wiggling like crazy compare to ours. Is this normal? Should I be concerned? Experiences? Everything was normal and we heard a nice clear 145 heart rate.
