What a shame that you feel already that you will have to fight with your "care" provider!
Initial questions for you:
- Can you take a childbirth class from an independent educator, one not affiliated with the hospital?
- Can you hire or get a doula?
- How supportive is your husband/partner?
- Is there a family practice doctor who takes care of pregnant women and who catches babies?
You can also plan to get to the hospital in very late labor (hopefully with the help of a doula) so that you are spending less time there. Less time = less possiblility for intervention.
Yes, you can refuse anything at any time. I do not believe that they can refuse to treat a pregnant woman regardless of how much "treatment" she refuses. I believe that's part of the EMTALA deal. (Emergency Medical Treatment/Active Labor Act) Now, they may make you sign a form saying you are doing things "against medical advice" (AMA) but I doubt it. Your doctor may decide to not care for you but somebody would have to take over your care.
Marsden Wagner, in his book Creating Your Birth Plan writes, "Any woman who finds herself laboring in an adversarial situation or confronting non-compliance with her wishes should repeatedly use such phrases as 'It's my right under the conditions of participation to decline a, b, or c procedures' or 'If you perform an intervention without my consent, I plant to file a complaint for violating my legal rights under CoP.'" (p247) The book is a gem. Get it if you don't have it already. Keep reading it if you do!
Again, getting there as late as you possibly can may just protect you against the interventions you mentioned ... until the baby comes out. Then you'll probably have to face another uphill battle. I tell my students, "Don't let go of the baby!"
