Baby movement and sleeping position

Hi mommies, recently I notice my baby will move the moment I am awake if I sleep on my left.. however if I wake up on my right, my baby doesn’t move and only move gradually when I turn to my left like warming up.. usually his kicks are hard and strong .. Anyone feel this way too? Or really my baby getting enough blood so he start moving again when I move turn to my left? I am kinda worried and wonder if it’s normal… #pleasehelp #advicemommies #firstmom
