Nah baby is SO well cushioned in there
I would be 0% worried
My 2 yr old done the same I’m now 22 weeks so i think you should be fine
My 2 year old and my 60 pound dalmatian did that during my second pregnancy and baby girl is here and doing great! Don't worry
Baby is well protected and comfortable,unless you are more than 29 weeks ...but till then it's okay x
My 1 year old does the same regularly and my little one is fine in there, I’m constantly on guard but he’ll just belly flop out of nowhere to get onto my lap or to climb over me etc, you’d know if it was reeeeally painful that something was wrong, that early on babies are nice and protected in the womb, I had a car crash at 12 weeks with my first and the hospital weren’t worried at all saying they’re very safe and snuggly in there that early on, I suppose just be glad they’re only 1! 😂
