No appointment until Dec 2 - is this normal?

Di • 32 - first baby due June 14, 2015
I got my BFP Monday eve and called my doctor yesterday.  About 5 weeks along. The receptionist called me back and booked the appointment for Dec 12 (knowing my LMP was Sept 5). But I know other girls who went at 6, 7, 8 weeks for their first appointment. Any idea why mines so late? Did they make a mistake with me?
