Identical twins do not share a sac during pregnancy. They each have their own amniotic sac and placenta.
Seeing only the yolk sac during an early pregnancy ultrasound can indicate that it is still very early in the gestation period, as the embryo may not yet be fully developed or visible. The yolk sac is essential for providing nutrients to the developing embryo before the placenta takes over. If there's concern about the pregnancy's viability or development, it's important to consult with a healthcare provider for further evaluation and guidance.
