1st appointment ?

My first appointment is thursday and I'm wondering what to expect .. I went to the hospital ( where I found out I am pregnant ) and they said to make an appointment for the next couple of weeks so I can get an US and actually see something on the screen .. I hope I get an US because I dont know exactly how far along I am & I dont want my SO to miss a day of work if its just gonna be paper work and stuff like that. Any ideas?
