As part of your preparations, you will be asked to attend with a full bladder. This is achieved by emptying your bladder 2 hours before your appointment and then immediately drinking 600-700ml of water.

Do not empty your bladder again before the procedure. You can eat normally and take any necessary medication.

Ultrasound is a non-invasive investigation to assist in monitoring your pregnancy. This examination may provide valuable information about your pregnancy that will assist the doctor in ensuring a successful outcome for you and your baby.
There are many reasons a doctor may request an ultrasound. Some of these are:

• To assist in determining the gestational age (when the baby is due).
• To assess the growth of a baby.
• To assess the number of babies.
• To check for possible abnormalities.
• To follow-up on any bleeding during the pregnancy.
