The first part of a pregnancy to be visible on ultrasound is the “gestational sac” which can be seen with a transvaginal scan approximately 3 weeks after a baby is conceived. During the next 2 weeks first a “yolk sac” and then a small “fetal pole” become visible.

When the fetal pole grows to more than 4mm the baby’s heart beat can be picked up on the ultrasound and these things normally occur 4 ½ weeks after conception (about 6 ½ weeks from the last menstrual period).

Approximately 99% of pregnancies in which fetal heart activity is found at 10 weeks of gestation will continue to term.
