When I had my DD, my 35 week chk had her in breech position. We were told she would have to be delivered by C/S if she was still in this position at my next chkup. I had read that spending a few moments throughout the day getting on to all 4's and moving about ever so slightly can help make the baby move into head down position. She did end up turning and we were able to go ahead with a normal birth. However she did move again slightly in labor and came out face up and to the side.
My best advice that I can give you is to listen to yourself about how you feel about your birthing options bearing in mind the advice of your dr.

I really hope bub turns out to be head down or will turn to be that way. All the best

Love Helen
