baby posterior (facing abdomen instead of my back) at 39 weeks

FTM here... Any moms on here that have given birth to a posterior baby? What was your experience?? 
my baby is still posterior and I am 39 weeks. From researching, I've read posterior babies will make labor much longer, with it being mostly back labor 😟.  I am planning for an unmedicated vaginal birth so I am concerned. I feel like I have tried everything to make my baby turn but she has remained head down & face up since 32weeks. Occasionally she will lay on her side, but never fully turns 😣.
