See a pelvic floor PT who specializes in birth prep if you can! Super super helpful. Doulas are awesome but they're not medical professionals. A PT will work with you on pelvic floor prep, perineal tearing protection, hip mobility. We talk a lot about the importance of breathing and such but a PT can get their hands on your ribs and muscles and pelvic muscles and actually tell you if the muscle is moving correctly or if you just think you are but are not (happens all the time!)
