on this question, you are also well recommended to check with the hospital you are delivering at as each hospital has its own rules.
you feel anxious to me which is understandable. in preparation and to reduce your concerns, perhaps take a site tour of the hospital and ask for as much information from your doctor as you can (they generally have lots of hand outs for you to read).
if you have not done so, I would also make a preference on the type of birth you want and write a birth plan. To find samples and templates... surf the web.
The above things all assisted me so hope the advice assists you.
take care, tnb
