Estimated Due Date: March 17
They may do some of the following:
  • Listen to the baby's heartbeat.
  • Check the size of the uterus.
  • Check for the baby's movement. (Mark on your calendar the 1st time you feel the baby move. Report it at your next visit).
  • Feel the baby through the abdomen.
  • Measure the uterine contractions and the abdominal size.
  • Do an ultrasound.

The due date is harder to set near the end of pregnancy.
This is one reason why early prenatal care is important.
