Have a look on the spinningbabies website.
33 weeks is still pretty early. He may still turn on his own you still have 6 weeks left.
Spinningbabies for sure. And if that doesn't work, push to try an external cephalic version early, like at 37 or 38 weeks. A lot of OBs won't mention that option till quite late, but it works best before baby is too big.
