Ultrasound in pregnancy
Most pregnant women will have an ultrasound scan during their pregnancy. This simple test is quite safe for both mother and baby and causes only minor, if any, discomfort. Ultrasound is a way of taking a look at the baby without using potentially dangerous X-rays.

The images will also be reviewed by a radiologist specialist in medical imaging and your obstetrician or midwife. Before having a pregnancy ultrasound, you are usually asked to drink several glasses of water and to hold off urinating for a period of time, so that you have a full bladder during the examination.

Your doctor or the ultrasound clinic or hospital where you are having the scans will give you instructions on how long before the test you should drink the water, and how much to drink.
Ultrasound scans are not painful. You may feel a small amount of discomfort associated with having a full bladder, or when having a transvaginal ultrasound. Pregnancy ultrasounds offer an opportunity to check that your pregnancy is progressing as expected and that your baby is healthy. Many people feel reassured to see images of their developing baby. If the ultrasound scan detects a problem, having the information early is often important.
