newCTmama- A doula is a wonderful support companion for a VBAC. I can't speak highly enough of how helpful ours was during our VBAC amongst hospital staff that was quite varied in their support/non-support. It super sucks that you can't determine the doctor that's on call, but you can definitely advocate for yourself no matter whom you have to deal with, and a doula is just the person to help. My DH was an extremely supportive labor partner, but for him to have some additional emotional support really allowed him to focus on our goals and to not feel overwhelmed. I hope you click with the doula you're meeting next week!
Also, my water broke after we had intercourse. It was a small gush at first, and completely clear...but then just gradually increased in volume and never stopped leaking. If it is indeed ruptured, I would highly recommend staying at home until active labor kicks in (unless you're GBS+ and planning on abx) so that no one can make you feel pressured to induce. Just my two cents. Good luck to you!
