Not sure if I should be worried or not.

Brittani
I'm a FTM and I'm 35 weeks and 3 days along. Usually my little babe is active here and there throughout the day and most active at night. Today she hasn't been as active as usual and has only slightly moved a few times. I'm still at work so unable to lay down in bed for her most active time yet. If she isn't active like usual when I am able to do so, should I go get checked? I am staying calm but am worried still. Any advice would be helpful. Thank you!
