Laura, don't stress too much. My mum had 4 of us (definately should have stoppe at one seeing as the quality deteriorated after the first...lol, of course me) and all of us were late turners.. well #3 get exempted as she was born at 33w... but the rest of us didn't go HDBU and stay there until the final week or so... #4 was completely breech on the Friday 40w3d and turned on the Sunday just before labour started.

A chiropractor trained in the Webster technique can help with turning bubs... everyone says the tip Shannon gave (all 4's) works well, even my ob and chiro, plus being in water a lot helps, something to do with gravity and preasure on the amniotic fluid but I can't really remember it well enough to explain... then there is sleeping with you legs slitghtly raised (but how comfy would that be now), sleeping with a radio between your legs.... shining a torch on the bottom of your belly near the cervix.
