Princess I was reading an article online:
http://pregnancy.baby-gaga.com/calendar/week25
It said that it's possible for baby to turn at any point after 15 weeks though not "engaged" yet. So your lil one could def be facing down though you still have a long way to go. And it's possible for them to move in and out of this position as the weeks go by.
HTH, thought I'd come back and post the link for ya.
