fetal pole, the first sign of a developing embryo, typically becomes visible on a transvaginal ultrasound at about 5 to 6 weeks of gestation, though it may not be seen until 9 weeks, depending on the equipment and the specific circumstances of the pregnancy, such as the angle of the uterus. Its appearance indicates a developing embryo and is often soon followed by a visible heartbeat around 6 weeks.
