Internal or external ultrasound?

I'm having my first ultrasound tomorrow, and we are really excited! I'll be 6w4d. As of 5w5d my hcg level was at 17,975 so that's why they decided we can do the ultrasound now rather than waiting til 9 weeks! Anyways, I'm curious for those that had early ultrasounds like this, was it an internal or external one?
