I'd recommend that you watch The Business of Being Born, and even if you can't have a MW and a homebirth, make sure you are prepared and armed by educating yourself on what your options are.
I don't know yet whether I'll be allowed to have a Home Birth myself, though I'm going to try for one and if I end up in the hospital I am hellbound and determined to know exactly WHAT they are putting into those IV's in my arm. A quote from the documentary I recommended
"It was very easy for them to do whatever they wanted, because I already had the IV in my arm."
Don't let them pressure you and don't let them force anything on you; that's one aspect where you are actually lucky being in the States -- the laws are pretty clear that in the field of medicine, anything done to a patient without their informed consent, is assault. If you're not comfortable with something, you do have the right of refusal. Make sure you're surrounded by people who will back you up on this as well. Uneducated but well-meaning "supporters" often will get confused and simply go along with whatever doctors say, operating under the assumption that "Doctors know best" -- Too often that imbalance of power, gets abused.
YOU know your body best... this is YOUR birth, You have the right to still give birth the way you want to, even in a hospital setting. Best of luck!
