Baby isn't moving

McKenzie • 19 year old first time mum and 22 year old first time dad excited to meet our little girl on Feb 5th or sooner ❤️
Hi Everyone, so I'm 31w5d and for a week now I've barely felt Bub move and today she hasn't moved at all. Has anyone else had this problem and everything been fine? My midwife said it could be her position but normally in the position she's in I can still feel her move.
Any advice?
