How Many Ultrasound Scans Do You Have During Pregnancy?

Throughout your pregnancy, you will attend regular doctor’s appointments to monitor the growth and development of your baby as well as your health as the pregnancy progresses. Ultrasound technology is one of the primary tool’s doctors use to monitor your baby. From ultrasound scans, they can glean a range of valuable information which will inform the doctor of any tests, treatments, and potential risks involved in the pregnancy. During your first doctor’s appointment, you may wonder how many ultrasound scans you have to have during pregnancy. The answer depends on you, your doctor, and your baby.

Why Do You Go for Ultrasound Scans During Pregnancy?

Women’s bodies are all unique, as are the embryos growing inside them. Doctors monitor women and their babies for variables and to ensure their health and safety. During this time, mothers are also afforded the chance to catch a glimpse of their baby and ask the doctor questions.

Ultrasound scans yield information such as:

  • The expected due date
  • Gender
  • Number of fetuses
  • Whether the baby is developing as expected
  • Is the heartbeat normal
  • Any obvious causes for concern

How Often Do You Go for Ultrasound Scans?

The intervals of the scans are dependent on the doctor and the information they gather from each consultation. Women who have miscarried previously, have pre-existing conditions, or are having their first child, may have to have more scans during their pregnancy. Women who are low risk and have had children before typically require fewer ultrasound scans, but it all comes down to the doctor’s observations, and the information yielded from previous scans and tests.

How Many Ultrasound Scans Do You Have to Go For?

Some women require fewer scans, but it’s always preferable to adhere to the doctor’s suggestions based on test results and risk levels.

Early Pregnancy Scan

Your early pregnancy scan may take place between 6 and 8weeks. Though scans conducted before eight weeks are unusual, in the case of high-risk pregnancies, the doctor may opt to perform a scan this early on to confirm the pregnancy viability and location. Once the pregnancy is seen inside the womb, then we can rule out an ectopic pregnancy.

First-Trimester Scan

Your first-trimester scan typically takes place between 11+1 and 13+6 weeks. This scan will coincide with the nuchal translucency test and detailed 1st trimester anatomy scan.

Second-Trimester Scan

This scan is usually performed between 18 and 20 weeks. This is when doctors find out the gender of the baby, check for abnormalities, and assess the amniotic fluid.

Third Trimester

During the third trimester the doctor will assess the baby’s growth; this scan will take place between 28 and 40 weeks. At this point, they will assess the size and weight of the baby, as well as how well the placenta is functioning.

Regular ultrasound scans are essential to ensure the fetus and mother are healthy and developing as expected. During this time, various other tests are also conducted to the same end. Should your doctor schedule your appointments at different times during your pregnancy, feel free to ask them about it – good doctors will always answer your questions and quell your concerns.

OMNI Ultrasound & Gynaecological Care

Condous performs Advanced Endosurgery procedures for women needing intervention for pelvic masses, adnexal pathology, severe endometriosis or hysterectomy. He also runs ‘Hands on’ Live Sheep Laparoscopic Workshops for gynaecologists at Camden Veterinarian School.
Having completed an undergraduate degree with the University of Adelaide, he left Australia in 1993 and moved to London where he completed his training in Obstetrics and Gynaecology. From 2001 to 2003 Condous worked as a Senior Research Fellow at St George’s Hospital, London. At St George’s he set up the Acute Gynaecology Unit, the first in the United Kingdom. It was also during this time that he developed an interest in Early Pregnancy and especially the management of pregnancies of unknown location (PULs). Condous has developed many mathematical models for the prediction of outcome of PULs which have been featured in numerous peer review journals. In 2005, he returned to Australia where he completed his Laparoscopic Fellowship at the Centre for Advanced Reproductive Endosurgery, Royal North Shore, Sydney.

Condous was appointed as a Consultant Gynaecologist and Senior Lecturer at Nepean Hospital in 2006 and soon was made Associate Professor. In 2010, he was made Departmental Head of Obstetrics and Gynaecology at Nepean Hospital. He obtained the MRCOG in 1999 and was made FRANZCOG in 2005. In 2009, he was awarded his Doctorate in Medicine (MD), University of London, for his thesis entitled: “The management of pregnancies of unknown location and the development of new mathematical models to predict outcome”.

Condous has edited three books including the “Handbook of Early Pregnancy Care”, published over 100 papers in international journals and is internationally renowned for his work in Early Pregnancy. He is the Associate Editor for Gynaecologic Obstetric Investigation, which is a European based journal, as well as the Australasian Journal of Ultrasound in Medicine (AJUM). He is on the organising committee and is an invited speaker at the International Society of Ultrasound in Obstetrics and Gynaecology (ISUOG) Scientific meeting in Sydney 2013. His current research interests relate to the management of ectopic pregnancy, 1st trimester growth, PULs and miscarriage and the use of transvaginal ultrasound (in particular sonovaginography, to predict posterior compartment deep infiltrating rectovaginal endometriosis).Condous is also actively involved with post-graduate education including the annual running of the Early Pregnancy and Gynaecological Ultrasound Interactive Courses for Sonologists, Radiologists, Sonographers and Gynaecologists in Australia.
