well welcome to mdc! i was terrified too, and frankly still am, but about different things :) but it's amazing and wonderful too.
just keep reading everything you can get your hands on, and thinking about who you and your husband are and want to be, and want your family to be, too. take everything you read or are told with a grain of salt, and follow your momgut [which you have, even now! :D ] on everything.
happy ttc'ing, and hope to talk to you again!
