Hi kirstenfleur,
I would definately be asking more questions and jumping up and down on this one. It is your choice whether to have the injection or not. The hospital may have it's own policies but you still should have a choice. If they wont budge you could look for another place to deliver. I am booked in to public hopital and put that I didn't want the injection on my birth plan and said I wanted a physiological third stage and it was no problem at all. I know that my hospital routinely gives the injection unless you specify that you dont want it. Hope I have been helpful.
