After emptying your bladder and wearing a gown you will lie on the bed and a special probe is positioned in your vagina. This has a sterile disposable cover. During this examination the vaginal probe is moved with varying pressure at different angles to obtain images of the uterus and ovaries. The sonographer will leave the room after the scan to review the images and to discuss them with the Radiologist. You will be given your expected due date on the day and will be able to take away images of the scan on our USB stick.

Occasionally there is some discomfort from probe pressure on a full bladder or from the vaginal probe manipulation. If this is extremely painful please let us know. An ultrasound scan uses high-frequency sound waves to create images of the inside of the body. Sound waves are used instead of radiation which makes them safe. Ultrasound can be safely used during pregnancy. You will need to arrive with a full bladder before you have your scan.

How is a dating scan performed?

A full bladder allows us to see your uterus and ovaries more clearly. We normally recommend that you have 2 glasses of water a half hour before you arrive for your scan. The sonographer will place gel on your tummy and which allows the probe to move more freely over your tummy.

Pressure will be applied but this is usually not painful to you or harmful to the baby. We like you to have a full bladder as it makes it easier for us to see your uterus and ovaries from across your tummy. We also have a look at your kidneys as occasionally the baby can lie on your ureter which drains the urine from your kidneys causing you some problems later in the pregnancy. So we like to know your kidneys are normal at the start of your pregnancy so if a problem arises later we know it is your baby causing the issue!

We like to do a vaginal scan as this gives us better visualization of your developing baby and where the pregnancy is developing in your uterus. You will be able to see the difference in the clarity of the scan across your tummy compared to a vaginal scan on our wall-mounted monitors. After your scan the sonographer will leave the room to discuss the images with the radiologist or obstetrician who may require more images to be performed.

This is normal practice and nothing to be alarmed about. Once you have been given your expected due date at your dating scan, the next scan will be the week scan.
