Apparently it's standard here in NL to have the first appt at 10 weeks, followed by an ultrasound at 12 weeks. I've been waffling on when I'll call and make my first appointment. I am in no rush, and the fewer appointments the better, in my opinion.
DH would definitely like the 12-week ultrasound. I'd just as soon not; there's nothing unusual going on, and I'm 100% certain on dates, but it's his baby too, and I'm not anti-ultrasound, so I imagine we'll do it. Though it may not be at exactly 12 weeks, depending on when I finally go in for an appointment.
