Decreased movement

Hi all, I’m 30 weeks pregnant. I had my 3 hour glucose test Friday which I passed with flying colors but ever since then baby hasn’t been as active. We also had an ultrasound that day and she was pretty active. I still feel her move and checked her heart rate on the Doppler we have at home (all seem normal). I’ve been told that baby could be going through a growth spurt or maybe just doesn’t have as much room to move. Anyone else experiencing this?
