2 ultra sounds

Im due in october. I called my doctor today for first appointment and she said she will see me at 8 week. And she will do both trans vaginal and abdominal ultrasound. Is this ok? Why is she doing both? Its my first baby and i dont have any previous medical history related to complication etc.

I always thought at 8 weeks she will be doing abdominal Ultrasound only. And is it ok to see me by 8 week and not early?
