I was told at my 32 week scan that baby was head down and happy. Unfortunately by my 36 week scan baby had turned around and was breech. I was scheduled in for an ECG (I think they only do this after 36 weeks). I decided to try accupuncture before the ECG and when I went for the procedure baby had thankfully turned. I don't think there is really any worries about breech babies until after 36 weeks. Until then almost a quarter can be in the breech position. Try to relax and visualise the baby turning. I hope it all goes well.
