Can they miss twins on scans?

For example, if your first ultrasound was taken prior to eight weeks of gestation it might have clearly revealed one distinct embryo. Yet, people who have twins missed at dating scan ultrasound later in the first trimester—or even into the second trimester—have been surprised when the second ultrasound clearly reveals two or more developing fetuses. Another fetus did not simply materialize along the way. Instead, the two-dimensional perspective of the first scan only caught a glimpse of one embryo.

The other was shadowed—positioned directly behind the other—and not visible from the view of the ultrasound tool. It is a similar effect to what we see during an eclipse. A hidden twin happens more often when the fetuses are and monoamniotic—sharing both the same placenta and amniotic sac. This forces the two fetuses to be positioned closely together; therefore, their shadowed position may not be detected in a quick scan.

What About the Heartbeat? There are also accounts of healthcare providers detecting a second heartbeat before they actually see the second fetus on an ultrasound. Not only are these incidents extremely rare, but they do not always mean that there is a hidden twin. It may simply warrant another look via ultrasound.
