No ultrasound or appointment before 12 weeks?

Is it normal for your OB to not see you for an appointment until 12 weeks? No regular check-in to confirm pregnancy on their end or discuss guidance, let alone an ultrasound. I called and asked if I can be seen any sooner and they told me they won't see me before 12 weeks, and if something seems off to go to the ER or call the nurse help line for an opinion. I see other people on here saying they got an unsound done at 8-9 weeks. 12 seems so long to not have any kind of appointment with my OB?
