decrease in baby movement 😥

Taylor • 🌸 🌞🌈
I'm 30 weeks and for the past couple days I've noticed a significant decrease in movement. I'll feel a few very faint flutters and kicks every so often. She was really active before, rolling and kicking the crap out of me! Should I go to the ER or just wait till the morning and call my doctor? I'm kinda nervous...
