An early pregnancy scan is a pivotal moment for expectant parents, providing valuable information about the progress and health of a pregnancy during its initial stages. Typically performed between 6 and 12 weeks of gestation, this ultrasound scan offers reassurance, detects potential concerns, and confirms key milestones like the baby’s heartbeat.
If it’s your first pregnancy scan, you might feel a mix of excitement and nerves. Understanding what to expect can help you feel more prepared and at ease.
Before the Scan: Preparation
The preparation for your scan depends on the type of ultrasound being performed:
1. Transabdominal Scan
- What to Do: You may be asked to drink several glasses of water before the appointment to fill your bladder. A full bladder helps push the uterus upward, improving image clarity.
- What to Avoid: Emptying your bladder before the scan unless directed otherwise.
2. Transvaginal Scan
- What to Do: No special preparation is typically needed. You may be asked to empty your bladder for comfort.
- Why It’s Used: This method provides clearer images during the early weeks of pregnancy, especially if the pregnancy is less than 8 weeks along.
During the Procedure
1. Arrival and Initial Steps
- You’ll be greeted by a healthcare professional who will explain the procedure and answer any initial questions.
- You’ll lie on an examination table for the scan.
2. The Scan Process
Transabdominal Scan:
- A warm gel is applied to your lower abdomen to help the ultrasound probe (transducer) transmit sound waves.
- The technician gently moves the probe across your belly to capture images of the uterus and developing embryo.
Transvaginal Scan:
- A slim, lubricated probe is gently inserted into the vagina.
- This method provides more detailed images of the uterus, gestational sac, and embryo during early pregnancy.
Both methods are painless, though the transvaginal approach may cause slight discomfort for some individuals.
3. Real-Time Viewing
- The ultrasound technician will show you live images of your uterus on a monitor.
- You may see:
- Gestational Sac: The first visible sign of pregnancy, usually seen by 5 weeks.
- Yolk Sac: Appears by 5–6 weeks, nourishing the embryo.
- Fetal Pole: Visible by 6–7 weeks, often accompanied by a heartbeat.
4. Measurements and Observations
- The technician will measure the crown-rump length (CRL) to estimate gestational age and confirm your due date.
- The baby’s heartbeat, typically between 110 and 160 beats per minute, is checked for viability.
What Will the Scan Reveal?
- Pregnancy Location: Confirms whether the pregnancy is in the uterus (not ectopic).
- Heartbeat Detection: Indicates a healthy and viable pregnancy starting at 6–7 weeks.
- Number of Embryos: Identifies if it’s a single or multiple pregnancy (e.g., twins).
- Gestational Age: Estimates how far along the pregnancy is and confirms the due date.
- Maternal Health: Checks for abnormalities like fibroids or ovarian cysts that may impact the pregnancy.
After the Scan
- Immediate Results: In most cases, the results are shared immediately after the scan. The healthcare provider will explain what the findings mean and answer your questions.
- Next Steps:
- If the scan shows normal results, your next routine scan will typically be scheduled for 12 weeks.
- If there are any concerns (e.g., no visible heartbeat or an ectopic pregnancy), your doctor will recommend follow-up tests or further scans.
FAQs About Early Pregnancy Scans
1. Is an early pregnancy scan safe?
Yes, ultrasound scans are completely safe for both mother and baby, as they use sound waves rather than radiation.
2. Can I hear my baby’s heartbeat during the scan?
In most cases, the heartbeat is visible but not audible during an early pregnancy scan. Sound capabilities are usually introduced in later scans.
3. What if no heartbeat is detected?
It may be too early to detect a heartbeat. Your doctor might recommend another scan in 1–2 weeks to confirm viability.
4. How long does the scan take?
The procedure typically takes 15–30 minutes.
5. Can my partner join me for the scan?
Most clinics allow partners to be present during the scan. Check with your provider beforehand.
Final Thoughts
