Obstetric (Pregnancy) Ultrasound
Services
Indications
Obstetric ultrasounds are recommended for:
- Confirm pregnancy and estimate dates (early viability/dating scan)
- Perform first‑trimester screening (11–14 weeks)
- Check baby’s anatomy (morphology scan around 18–22 weeks)
- Monitor growth, position, placenta and fluid later in pregnancy
- Assess symptoms such as bleeding or pain
What is an Obstetric (Pregnancy) Ultrasound?
This is an ultrasound during pregnancy to check your baby’s growth and development, the placenta, amniotic fluid and your uterus. Most scans are done on the tummy; in early pregnancy, an internal scan may be suggested to obtain clearer images. The scan can show baby’s heartbeat and movement, number of babies, growth, anatomy, position (breech or head‑down), placenta location and fluid levels.
Finding the baby’s sex is sometimes possible, depending on the stage of pregnancy and baby’s position. Ultrasound in pregnancy is considered safe when used for medical care by trained staff and there is no radiation.
What Can I Expect During the Test?
For early pregnancy we usually ask for a comfortably full bladder; later on it is usually not needed. Gel is placed on your tummy and a small probe is moved gently to see the baby. If the baby’s position makes views tricky, we may ask you to change position or have a short walk. Very early in pregnancy we may offer an internal scan for clearer pictures—this is optional and explained first.
Depending on the stage, we may confirm the pregnancy and due date, do an early check around 11–14 weeks, take a detailed look from head‑to‑toe around 18–22 weeks, or check growth, fluid, placenta and baby’s position later on. Most scans take 30–45 minutes and there is no radiation.
What Are the Risks of the Test?
Obstetric ultrasound is extremely safe with no known risks to mother or baby when performed for medical purposes. Extensive research over decades has shown no harmful effects from diagnostic ultrasound during pregnancy. The procedure is painless, though you might feel slight pressure from the transducer. The full bladder required for some scans may cause mild discomfort. There’s no radiation exposure, making it safe to have multiple scans if medically necessary throughout your pregnancy.
Preparation
(This test will take 30-45 minutes)
Early pregnancy (up to ~14 weeks): Please drink water beforehand and arrive with a comfortably full bladder (we’ll advise amounts when you book).
Second/Third trimester: A full bladder is usually not required.
Avoid applying heavy creams or oils on your abdomen on the day—they can affect image quality.
You may bring your partner/support person if you wish (space permitting).
