Pregnancy is a time of joy, anticipation, as well as anxiety. Especially during the early weeks of pregnancy, many expectant parents feel a mix of joy and concern as they wait for signs that everything is progressing as it should. One way to gain reassurance and vital information during these early weeks is through an early pregnancy scan.
In this article, we’ll explore what early pregnancy scans are, why they are so important, and what expectant parents can expect during this critical phase of their pregnancy journey.
What is an Early Pregnancy Scan?
An early pregnancy scan, typically carried out between 6 and 10 weeks of pregnancy, is a routine ultrasound that helps to assess the health and development of the pregnancy. This type of scan is not only important for confirming the pregnancy but also provides essential information about the location and viability of the embryo or fetus.
The primary goal of an early pregnancy scan is to ensure that the pregnancy is progressing normally and to identify any potential issues early on. For example, one of the key functions of this scan is to rule out an ectopic pregnancy, which is a serious condition where the embryo implants outside the uterus, most commonly in one of the fallopian tubes. Ectopic pregnancy are extremely risky and require prompt medical intervention.
Why Are Early Pregnancy Scans Important?
There are several reasons why early pregnancy scans are highly beneficial. One of the most significant reasons is the reassurance it offers to expectant parents. Many parents, particularly those who have experienced previous pregnancy loss or are undergoing fertility treatments, seek early confirmation that the pregnancy is viable.
For many, the presence of a heartbeat during an early scan provides a much-needed sense of relief. According to Tommy’s, a UK-based charity dedicated to reducing miscarriage and stillbirth, the risk of miscarriage drops significantly—down to around 5%—once a heartbeat is detected at 8 weeks.
Early pregnancy scans also allow healthcare providers to confirm the number of embryos in the uterus. If the ultrasound shows more than one gestational sac or heartbeat, this indicates a multiple pregnancy (twins, triplets, or more). Detecting multiples early on helps in planning appropriate prenatal care, as multiple pregnancies often come with additional risks and require closer monitoring throughout the pregnancy.
Another important reason for early scans is to estimate the gestational age of the fetus. While many people use their last menstrual period (LMP) to estimate their due date, this method is not always accurate, particularly if a woman has irregular periods. An early pregnancy scan can provide a more precise estimate by measuring the size of the embryo and confirming the stage of development. This, in turn, helps healthcare providers plan the best time for future tests and scans, such as the nuchal translucency scan and anomaly scan, which are typically performed later in the first and second trimesters.
What Happens During an Early Pregnancy Scan?
The procedure for an early pregnancy scan is similar to other routine ultrasound scans, though it may sometimes require a transvaginal ultrasound for a clearer view, especially in the very early weeks of pregnancy. A transvaginal scan involves inserting a small ultrasound probe into the vagina to get a better view of the uterus and embryo, and it is completely safe for both the mother and the developing baby.
During the scan, the sonographer will check for several key things:
- The pregnancy’s placement –is used to rule out an unplanned pregnancy.
- The presence of a fetal heartbeat – this is usually detectable by around 6 weeks of pregnancy.
- The size and development of the embryo or fetus – this is used to estimate gestational age and confirm due dates.
- The condition of the ovaries and uterus – to identify any potential complications, such as ovarian cysts or uterine abnormalities that could affect the pregnancy.
Most scans take around 15 to 30 minutes, and while some women experience mild discomfort, especially with transvaginal scans, the procedure is generally painless.
When Should You Have an Early Pregnancy Scan?
Early pregnancy scans are typically recommended between 6 and 10 weeks of pregnancy. However, some women, particularly those with a history of ectopic pregnancy or other complications, may be advised to have an even earlier scan.
Private clinics, like the London Pregnancy Clinic, offer early pregnancy scans as part of their antenatal services, helping expectant parents gain reassurance during the crucial early weeks. While early scans are not always offered as standard by the NHS unless there are specific concerns, private scans can offer peace of mind.
What Are the Risks of an Early Pregnancy Scan?
Ultrasound scans, including early pregnancy scans, are considered very safe. The use of sound waves, rather than radiation, means that there is no harm to the developing baby or the mother. However, it’s important to note that early scans may sometimes cause unnecessary anxiety if the results are inconclusive. For instance, a scan performed too early may not detect a heartbeat simply because the pregnancy is not far enough along.
In such cases, your healthcare provider may recommend waiting another week or two before repeating the scan. Rest assured that most pregnancies progress normally even if the first scan does not show everything expected.
Conclusion
Early pregnancy scans offer invaluable reassurance and provide critical information about the health and development of the pregnancy. Whether you are looking for confirmation of a heartbeat, ensuring the pregnancy is in the right place, or simply wanting to know your due date, early scans can provide the peace of mind many expectant parents seek.
If you’re considering an early pregnancy scan, consult with your healthcare provider about the best timing and what to expect.
