Ftm need advice

ka

I've been up for almost 3 hours now and have only felt my baby kick once. I've drank juice and have eaten. I used my fetal doppler and his heartbeat sounds great resting at 153 but he isnt moving. Idk what's normal for late pregnancy cuz I know there isnt much room in there for him to move around. I need advice cuz I'm stressed 😬 I'm 36 weeks pregnant.
