First Prenatal Appt?

I'm 9wks 4days pregnant with baby #2. I had my first appt at 7wks 4days. I got all of my blood work, my paperwork & had my first ultrasound on that day. The only thing I didn't do was meet the doctor (he was called away on an emergency c-section). I got to meet with the head nurse and she answered every possible question I could possibly ask! lol. She was excellent! They scheduled me for my next appt tomorrow at 9weeks 5 days. But what should I expect? I thought everything was done. What else will they be doing? They discussed sending me to a specialist because my first daughter was a small baby 5lbs 3oz. I had Gastric Byp surgery in 2002. So they want to monitor this baby's size very closely. They called this my "First Prenatal Appt". Anyway, any ideas what will be done?
