Baby movement

I recently had an untra sound. I am 8 1/2 weeks along. The baby had a good heart beat 172, but it did not move at all during the ultra sound. I am worried because when I had an US with my daughter at about the same gestation, she was wiggling like crazy.. Should I be worried?

Hi!
If the baby was measuring appropriately and had a good heart rate, there is nothing to be concerned about.  Babies have sleep cycles that last approximately 20-30 minutes, and they hold still when asleep.  Its quite possible that this new baby ( a boy?) was just sleeping.  I 'm sure that there will be more than plenty of activity down the road!

Congratulations!
