Hiring a doula?

Alyssa
Anyone plan or have hired a doula? Ill be 38 weeks on Sunday, and I have concerns about my doctors not honnoring my wishes to vbac. I've read that having a doula can be really helpful. I don't even known if it is too late in the game to hire one, but share any experiences you might have with hiring one, and how it made a difference in your birthing experience.
