Second scan

Went for my first gynae appt yesterday. Doctor said I'm just 6 wks through transvaginal ultrasound. Next appt is on 9 wks. Will there be any issues if I postpone my second appt to 12 wks so I can skip transvaginal scan? It's kinda painful / traumatizing for me.. Maybe I just didn't do enough research and got a shock that I had to do a transvaginal scan on my first appt. But I don't really want to do it again lol #firsttimemom #advicepls
