Decreased fetal movement

I’ll be 38 weeks tomorrow. I’ve noticed a big decrease in my baby’s movement. She went almost majority of the morning without moving. Once i realized it, i started doing kick counts because she’s normally bouncing all around after i eat. I’ve ate breakfast and a sugary candy to see if she’d move... nothing. I ate some ice and she did start rolling around and kicking a bit. Is this normal this late in pregnancy or does it draw a red flag that i should be concerned with?
