DD2 was transverse or breach until 36 weeks, she kept flipping half way. Then I started crawling around the floor alot (although not easy with SPD) and I was doing mini handstands in the shower at night and she flipped just after 36 weeks
I'm getting the most interesting visials from your post mel

My little one is breach right now too at 29 weeks. I was told not to worry about it until 34-36 weeks as it will more than likely turn.

Thinking of you though and sending 'spinning' thoughts xx
