sleeping position

Hi! I am 22 weeks pregnant. I can feel my baby's strong kicks or maybe him just spinning around. Right now I am trying to find my comfiest sleeping position for my baby. When I lay on the right side I feel that he is uncomftable because kicks so hard and I feel that my tummy gets hard or is it cramps? So I try to change my position to the left side. Right now I feel his kicks and again that pain on the sife of my tummy.
