finally got my first mid wife appointment!

So finally got an appointment with the midwife for next week. After talking on the phone, she thinks I might be 12 n half weeks! Although I only got a BFP at the weekend after not testing for a week. 
I've got a scan booked in for straight after too, so really nervous and excited all at the same time! 
What should I expect on my first appointment with the midwife? What will she do?
