Posterior baby

Br

I’m 34 weeks and baby’s head is down but she’s sunny side up. The kicks are intense!! My uterus feels bruised. Anyone else’s baby posterior? I’m surprised she is, I’m very active and have been working out my whole pregnancy and from what I read on how to flip her, is staying active and keeping good posture. Anything else?? I heard labor is longer with posterior baby’s and I’m freaking out.
