Pingu - DS was bum down at 36 weeks! I hated the idea of a doctor attempting manual turning (ECV), so I was to be booked in for a CS.
I was pointed towards spinningbabies.com and spent a week doing the exercises to encourage turning lots of sticking my arse in the air much to DH's amusement, but never felt any big shifts.
The day I went in to do all the documentation for the section, I although I hadn't felt him turn I asked if they'd do a quick ultrasound just to check. Despite the midwife saying there was 'no way' he could have turned without my noticing, she indulged me, and lo and behold he had, and the 45mins worth of CS booking has been totally pointless! I was too elated to care 
So yes, very much recommend the spinning babies site, have a read of the 'Flip a Breech' page. Fingers crossed for you!
