Masterbating while pregnant.

Has anyone felt and seen the baby move to the bottom of belly after masterbating?? Is that normal?? I feel like I’m hurting my baby but I don’t know. I’ll have a full big belly all around, then once I’m done masterbating the top of my belly ups flat and the baby looks Like it’s in a little ball by my belly button.. kinda hard to explain it.. but should I worry??
