Early pregnancy ultrasound findings and pictures at 5 to 6 weeks. Five week pregnancy ultrasound with sac and yolk sac. Transvaginal ultrasound, normal pregnancy at 5 weeks 2 days. Gestational sac (black area ) and yolk sac are seen. Sac measures 6.25mm diameter. Yolk sac (small white circle in left side of the sac)
Artificially colored, showing gestational sac, yolk sac and embryo (measuring 3 mm as the distance between the + signs).
