When you say you dont have your own OB, do you mean your going through an antenatal clinic at the hospital, or doing midwife only care, shared care etc?
It depends on the hospital, OB and how assertive you can be. They may not do it before 40 weeks though. Id get the physio to put something in writing or speak directly with your care provider, and if you arent happy with their response ask whom you need to speak with.

Kim - I would have made a complaint regarding your care with DD1 if you had those symptoms i dont know what reasoning they used not to let you be induced?
