Every baby is different and baby has lots of room to mobe around yet and is growing right now so baby will be sleeping a lot of the time.
Don't stress! Most women don't feel much of anything until 24 ish weeks during their first pregnancy.
It's still kind of early I didn't feel my baby normally til around 25 weeks. I had my ultrasound when I was 21 weeks and I seen her movements on the screen but i didn't feel them. Don't stress everyone's body is diff so people will feel their babies at diff times
