You've got time, which is good

Lots of walking, sitting forward....

Some yoga positions are very helpful for this sort of thing. There are books on fetal positioning...I believe one i have is called "optimal fetal positioning"....a library only rarely has such useful books...an on-line bookstore may have some good ones. Capers is great, but expensive.

Babies usually only go head-down around now anyway, so chances are, within a few weeks, bubs will be in a great position for birth...but yes, do look up some excercises or the like to try. Good luck!
