How To Prepare For Your 10th Week Scan?

To prepare for this scan, consume enough water to keep your bladder full. This is essential for getting a clear picture of the baby, uterus and cervical region. Drink water at least one hour before the scan for an accurate image (3).

The Ultrasound Procedure

During an ultrasound, you will lie down with the abdomen exposed for the procedure. The sonographer will apply a special gel on the abdomen and pelvic region. Then a small wand, known as the transducer, is moved over the abdomen to capture the images on the screen. You will be asked to hold your breath while capturing the images.

Once the necessary pictures are taken, the sonographer wipes away the gel, and you may empty your bladder. In some cases, if the abdominal scan cannot give clear images, a transvaginal scan is suggested (2).

What Is The Duration Of The Procedure?

The ultrasound procedure lasts around 20 to 30 minutes (4). Sometimes, it might take longer if the baby is in an unusual position, or very actively moving around. If the scan is not giving clear pictures, it may have to be done again.

Don’t worry if you cannot see the baby moving in the 10th-week scan. The movements are subtle at the beginning, which is why you might not feel them. As the pregnancy progresses and the baby grows, the movements become stronger and more evident. In some cases, your doctor may get another scan done in the same week.
