Plus Size Ultrasounds?🤔

I'm a plus size woman & pregnant with my first. I actually don't carry a lot of fat in my tummy like around my uterus area, but I have my first ultrasound scheduled for next week & im wondering & worrying if my weight will cause problems for the ultrasound tech. Will they be more prone to use a transvaginal ultrasound & if so does it hurt? What was your experience?
