When should I get an ultrasound during pregnancy?
Sometimes a pregnancy is unplanned, and an ultrasound is needed to figure out just how old the baby is and when the due date will be.

What happens if the baby does not cooperate with the ultrasound?
As with all ultrasounds, the baby does not always fully cooperate with the technology. There are instances where a sonographer will not be able to find a limb of the fetus. If a limb or part of the baby is not detected in the first trimester it does not necessarily mean that the child will be born without it.
