Baby’s movement

Hi mummies, im at 33weeks my baby doesn’t really move much the entire day. He will be active for maybe a few mins and then not much movement anymore. Does anyone else have the same problem? Seems like he likes sleeping alot ? not sure if i should be worried as he has been like that since i can feel him moving. He likes to pause his movement and sleep on one side of my body too ? although he does move back to the middle when i give him a little nudge
