Yeah - breaking water can be a better point to start induction at too. For me that wasn't an option because my water was mostly gone anyway (so I wasn't actually being induced) and even though I'd been contracting strongly for probably 24 hours I wasn't dilating.
Also - when I was so worried about induction it REALLY helped calm me down to read as many stories as I could find about positive natural birth experiences with an induction. I studied Hypnobabies, so those were mostly the stories I looked up. There are a lot on the Hypnobabies website and also a lot here (there's some overlap with the HB site I think but some unique ones too). It really comforted me to know that there WERE women who were able to still have positive natural births even when induced.
And also... I know that right now, preparing for it, this isn't what you want to hear. But having spent my whole pregnancy preparing for a natural hypnosis birth, and then having a birth experience that was dramatically different from anything I had envisioned and very, very difficult on a number of levels... an epidural isn't the end of the world. I still believe that a med-free birth would have been the best thing all around for me if the situation had been different, but with things the way they were, an epidural was really a wonderful thing. There is definitely a time and a place for pain meds (and other interventions as well, obviously). But I'm SO hoping first of all that you don't have to be induced, and second of all that if you do need to, you will be able to still have a birth that is very close to what you envision!
