Baby overdue and disengaged?

Samantha
Really weird, babies head has been 'engaged' now since 37 weeks and gradually moving up the scale - two weeks ago the midwife said I was 2/5 engaged which was a steady progression so I felt on track! Went to see doc this week and she has put in my notes the babies head is 'free' so completely out!! Considering it was my due date I was pretty surprised and disappointed.. is anybody in the same boat? Can they just reverse like that? Am now overdue and looking for ways to help ease her back on the right tracks - anybody had a similar experience or advice? I've been walking miles, bouncing on ball, squatting, yoga, acupuncture and reflexology and she's still really high up- any advice out there?
