gracie - sorry to hear that bubs has turned posterior
i think mine is posterior too (after spending MONTHS perfectly positioned at the front on the left!). my OB told me not to bother worrying about it though because babies can (and often do) turn at the last minute to the best birthing position at the onset of labour... i'm not sure whether he was just trying to make me feel better or not, but have decided not to worry about it anyway!!
