Why is my belly still sitting so high??

Ni

38+5 today and my belly is still so high. His butt and feet are in my ribs and no sign of him moving down. I’m only 5’0 so not much room for him to begin with...Due Sept 20 and my midwife told me to start inserting evening primrose oil vaginally at night and pumping twice a day. 🥵😭
