dont worry you will most likely be sore afterwards but nothing will stop you from concentrating on your new baby!

try not to focus on the pain side of things, one way or the other your baby HAS to come out and you will get through it. and if you have the epidural it shouldnt hurt at all anyway.

i was a lot like you for first birth and your right its more about 'not knowing', so all i can suggest is be open minded, go with the flow and try to relax!

all the best! :-)
