Excessive fetal movements 10w6d

Hilary
Had an ultrasound today and the baby was flipping and kicking all over the place like a little Bruce Lee! The doc couldn't get any fetal measurements or even take a pic bc the baby just wouldn't stay still for even a second. Doc said the baby seems good and appears the size it should be, even tho he couldn't get measurements. 
I'm just curious if anyone knows if these excessive movements indicate anything in particular. Possitive, negative? Anyone else have such an active little bugger at 11ish weeks?
