First appointment(s)?

Lauren
I have a question.  I just made my first (3) appointment with my OB.  Why do I need 3 appointments?  The first is a pre natal physical on 11-2 (8weeks) and then another appointment on the 11-12 and another with the actual doctor on 11-31.  Is all of this necessary? I also asked if I would be getting an ultrasound but they told me not until around 18 weeks.  😁  I am going to be asking about it when I go on the 2nd.  But anyone else experience this?
