Transverse can be normal up until this point, but if you're having any lower back or hip pain with it, you need to get treated as soon as possible. Dr. Carol Phillips in Annapolis is, IMHO, the best anywhere around here. She's a chiropractor who specializes in pre-natal techniques, especially baby positioning. She goes all over the world teaching her techniques and is just excellent (and one of the nicest medical professionals you'll ever meet---she's also been a doula at over 700 births and is very pro-natural birth to boot :). Her treatments are gentle and involve a lot of massage (she does cranio-sacral and myofascial release techniques as well). Straight chiro didn't help me, but her techniques worked like magic and felt sooooo good! She's totally worth the drive from California (she has pregnant patients who travel in from other states!)
I saw her for help after my 3rd baby (first two were also malpositioned) was transverse starting around week 32. I did the techniques on Spinning Babies but realized around week 37 that I needed more help. I found Dr. Phillips' name as the one who trained the Spinning Babies webmaster. After two visits with her (each a little over an hour) my son turned head down, stayed that way, and I had my first "normal" labor after my previous two had been excruciating back labors with extended pushing. I almost didn't make it to the hospital in time---the pain was so much less and pushing took 10 minutes! My best birth ever
You need to know, too, that sitting transverse or in any funny position can affect the development of the baby's neck muscles. Dr. Phillips warned me to watch for signs of torticollis (or wry neck), and sure enough, my son did have it slightly. I really wish I had found her earlier and that would have saved the treatment my son needed for his torticollis. The sooner you get your baby's position remedied, the better.

She has a link to her appointment calendar there, but if you can't find openings, she has her phone number there. Don't hesitate to call her and ask about any additional times she may have open. She's really eager to help any pregnant patients that she can.
Best wishes for a smooth delivery!
ETA: Dr Phillips has an excellent success rate in healing moms so babies can turn themselves. She recently published a study in a chiropractic journal documenting some of her successes, and I'm one of her case studies :)
