What is a vaginal ultrasound like?

Speculum exam?: Maybe one of the female physicians can answer this better than I, but I would expect that it would be similar to a speculum exam by a gynecologist. It is a probe, designed to go into the vagina that allows the physician to see what's going on inside your abdomen. It is much closer to the abdominal structures so tends to give a better view of certain things when transabdominal U/S fails.

Vaginal ultrasound: The probe utilized in a vaginal ultrasound is placed into your vagina. It is approximately the diameter of a quarter. It provides a closer look at an early pregnancy as well as evaluation of pelvic organs.
