I think it depends on your OB a little. It's probably easier for them to do an internal at the first one incase you're measuring off from your LMP EDD.
My OB is having me drink a ton of fluid about an hour before my ultrasound so she can do an external. Of course, if I have to pee, I'm going to pee, so she may have to do an internal. My first ultrasound will be a little after 7 weeks.
