I was just as confused as you are right now when I was 1st pregnant with this baby! I honestly felt like It was my first pregnancy all over again! Thats how I came to find this lovely place (BB) and the wonderful world of knowelege and support!
In the end, I had to pretty much demand information from my ob's receptionist about what appointments, when.. I'm still taking a list of questions to every appointment, but at least now, I know what tests and appointments are due when, Most other things I have learnt from stalking the forum and especially my BB group.
I know what it is like to have your heart set on something, (like which hospital you want to go to) I wonder if it would work to tell them you want to go to the other one because you will be moving at some time during your pregnancy and you will have to go past this one to get to the one they want you at???
Have a look for a birth centre near you, they will give you heaps more support, A doula in your area would also be a big help and would proberbly have a pretty good idea to guide you through till your on your knowelege feet (so-to-speak)
Good luck, and as the others have said, just enjoy your pregnancy , everything will soon become alot clearer to you!!
