Jenny, I'm starting my 33rd week tomorrow and my doctor hasn't been concerned with my baby's position, yet. He said they still have plenty of room to flip and move all over. At my last three visits he said he believes that she is head down, but he also said that means nothing at this point. I've even heard of one person whose baby COMPLETELY flipped after she went into labor.
Just don't stress over it, yet. You have another 5-6 weeks to go. Good luck!
