Heh, there was a lady in my daughter's
PR that had four c-sections, and was going to have her fifth. She went into labor early, and when she said she was scheduled for a C-section on such and such day and needed one NOW, the doctor was like "well, let's try and do it vaginally.. PUSH." She labored for a while (I believe the OR was booked already), and they finally got her in for a C-section. I wish I could find the birth story.
But I was just thinking that I want THAT doctor. "Four previous C-Sections? Oh well. PUSH MAMA!"
Anyways, my point is that they can't force you to have a C-section without a court order, but it IS important to have a supportive doctor and nursing staff. A lot of women would cave under constant pressure to have a C-section (I probably would).
I second the suggestion of checking out ICAN, and maybe shopping around for midwives. if you can't find a supportive medical practitioner, I suggest looking for a doula to be there when you go into labor - that way you have someone on your side when the nurses are breathing down your throat.
