Anyone else having the same?

Hey Mumma's,  
I'm 36 weeks and feel like baby is just pushing down into my pelvis / bladder she is constantly moving (Not moaning at all!!) but it's like she takes a massive run up and then runs head first into my pelvis. Do you think she is trying to engage? 
Had a scan and they struggled to scan her head alas she was so far down!
