Movement?

Sasha • First pregnancy! Due on the 4th of December with a baby girl👼🏻
I've just come to realise I haven't felt any movement today, and it's 2:13pm. Even when I rubbed her foot she didn't move it (a bit odd). I'm 38 weeks & 1 day. Has anyone else had this? 
It's a Saturday so I don't really want to call my midwife on her day off😓
