First ultrasound, what to expect?

Hello mama’s (to be), I’m going for my first ultrasound tomorrow and I have no clue what to expect/see. I’ll be 5 weeks and 5 days and it will be a transvaginal(?) ultrasound. Did you see or hear the heart beating? I know you won’t be able to see too much but just curious if you saw the heart by then.

UPDATE: had my first ultrasound, there’s a baby in there and his or her heart just started beating.
