Jenna was head up at her 26 or 30w appt, I can't remember which one, and head down at the next appt. I wouldn't stress too much about it until it gets closer to the date.
Even if they do decide to book you in fora c/s at 38w, baby has every opportunity to turn before then, and if turned it will mean that they wont go ahead with the c/s.
I'm sure it will be fine!
