Would this ultrasound be vaginal? Or abdominal?

My husband and I are TTC. Our next step is going to be a couple rounds of letrozole with the trigger shot. My Dr said once she gets my lab results back, I will start the letrozole, she will schedule the ultrasound to check my follicles, and order the shot.

I have done 5 rounds of letrozole before, but never had to do this ultrasound and trigger shot.

Would this be a vaginal ultrasound?
