I realized when I put my hand in my belly and went to a quiet room and drank something cold while laying done or maybe even sitting down my baby would move I thought my baby wasn't moving but she was I just had to really concentrate and feel my belly with my hand if not I would of probably not felt her but I have an interior placenta idk if u do too and yesterday I turned 25 weeks and my baby kicked me so hard through my shirt for the first time and she did it again today I say go somewhere quiet drink something cold place your hand on your belly and just concentrate and u will feel movement it may take a while tho
