31 weeks and 3 days pregnant with no fetal movement| I can't find my baby's heart beat| L&D

hi everyone, so for the past 3 days I have not felt Gee move much. typically he moves a lot, and when I wake up, he wakes up too. He has not done that over the last few days. last night I woke up out my sleep with worry because I had not felt him move. I grabbed my doppler and I was immediately able to find his heart beat. Today, I believe I felt him move earlier. I was so exhausted I took a nap and again when I woke up I didn't feel him move. This time I attempted to find his heart beat, and I could not find it. I'm going to the Labor and Delivery I pray all is well.
