How much movement is normal?

Chey

I am trying not to be a worry wart, but I feel like my little guy doesn’t move THAT much? Sometimes he is very active but usually I just feel small movements here and there.. everyday I feel him but I just feel like he doesn’t move that much and it makes me worry.. I’m 27 weeks today. Yesterday we had an ultrasound and baby pretty much was curled up in a ball the entire time sleeping. What’s normal? Should I be trying to count his kicks and movements I feel??
