Baby movement

Stefanie
So Monday 36 weeks 1 day I got sent to hospital for 24 hr observation because baby B was being lazy and didn't want to move for ultrasound. She decided to perk up and act normal while we were at the hospital so we got sent home. Now I am super paranoid that something is wrong if they don't move a lot and I've read that towards the end babies start to slow down with movements anyways. I've gone almost my whole pregnancy without drinking soda or caffeine but now I feel like I need to drink it to keep them moving... Am I overreacting? Does anyone have any suggestions to help me relax and stay calm or suggestions to help baby movement? Changing sides doesn't work and neither does ice water.
