You will be asked to drink about two pints of water before the scan to fill up your bladder; this pushes up the uterus to give a clearer picture. Youll then have gel rubbed onto your belly and a hand-held scanner passed smoothly backwards and forwards over your skin.

How much water do you drink before a pregnancy ultrasound?

You can eat before your ultrasound. You are required to have a full bladder. It is necessary to drink 600-800ml of water two hours prior to the scan and refrain from going to the toilet before the scan.
