Fiona was breech (but mostly transverse).
We went with the external version.
My doctor won't perform a version UNTIL 37 weeks at the earliest, as it can send you into labor, and she doesn't like things to be any riskier than it has to be.
I experienced absolutely no pain, and Fiona was turned within 3 minutes. Her heartrate never even wavered (but she's a pretty laid back kid). In retrospect I'm glad we did it, it eased my mind (although I had to have an unexpected cesarean anyway due to other reasons).
I felt comfortable with the version (despite all the horrible scare stories I read about them online) because my doctor is/was extremely experienced in both the version technique AND the delievery of breech babies vaginally--so I knew she would not push me towards an elective cesarean.
Weigh all your options before you make a decision, and you might as well try some of the 'home remedy' type of things, as they don't hurt and are free.
