Ultrasound scans may be used to:

  • Confirm your due date, by measuring the size of your foetus
  • Confirm if you might be carrying more than one baby
  • Check for any intrauterine device that may have been placed as a birth control method
  • Monitor the growth of your baby
  • Detect any abnormalities of the foetus
  • Offer a window to the womb during an amniocentesis or chronic villus sampling
  • Measure the amount of amniotic fluid in the womb
  • May detect the source of any abnormal uterine blood loss
  • Check for a molar or ectopic pregnancy, or a miscarriage in case there is no movement of the foetus by the 22nd week, or if the movement has stopped.
  • In some cases, determining the baby’s sex. Although, the accuracy of this highly depends on the position of the baby and the skills of the person conducting the ultrasound
  • Access the condition of the placenta if the baby is small
  • Determine the state of the cervix, if by any chance it has started premature dilation
