Introduction to Early Pregnancy Scans
An early pregnancy scan is an essential step in confirming and monitoring the health of a pregnancy during its early stages.
Typically performed between 6 and 12 weeks, this scan helps confirm the pregnancy, estimate the due date, and ensure that the baby is developing normally.
Whether it's a viability scan, dating scan, or ultrasound scan early pregnancy scans offer valuable insights that can guide medical decisions and provide peace of mind to expectant parents.
When to Book an Early Pregnancy Scan
An early pregnancy scan, also known as a viability or dating scan, is typically conducted between 6 and 12 weeks of pregnancy. The timing and purpose of the scan depend on various factors, including your medical history and any symptoms you may be experiencing.
Please consult your primary physician or gynecologist for scheduling your Early Pregnancy Scan and understand if there are any specific details based on your medical history that the doctor would like to ascertain from the USG scan.
What Happens during the Early Pregnancy Scan
Early pregnancy scans are performed in one of two ways: transabdominal ultrasound or transvaginal ultrasound. The method used depends on how far along the pregnancy is and the clarity of the images needed.
1. Transabdominal Ultrasound
- How it’s Done:
- You lie on your back, and the radiologist applies a gel to your abdomen.
- A handheld device called a transducer is moved over your abdomen to create images of your uterus and pregnancy.
- Preparation:
- A full bladder is often required to help improve the clarity of the images.
2. Transvaginal Ultrasound
- How It’s Done:
- You lie on your back, and a thin, wand-shaped transducer is gently inserted into the vagina.
- This allows for closer imaging of the uterus and developing pregnancy.
- Preparation:
- A full bladder is usually not required.
- You may be asked to undress from the waist down and cover yourself with a sheet for comfort.
Preparing for Your Early Pregnancy Scan
Preparing for your early pregnancy scan is an important step to check on the health of your pregnancy. Here’s how to get ready
- Drink Water: Drink plenty of water about 1-2 hours before the appointment to help make the images clearer.
- Wear Comfortable Clothes: Choose easy-to-remove clothing for comfort.
- Expect Emotions: It’s normal to feel excited, nervous, or emotional. The scan might show the baby’s heartbeat or confirm things like the due date.
- Ask Questions: If you're unsure about anything, ask your radiologist. They can explain the process and the results after the scan.
Steps to Take Before the Scan
Before your early pregnancy scan, it's helpful to follow a few steps to ensure the process goes smoothly.
- Follow Specific Instructions: Drink water if required for a transabdominal scan or empty your bladder for a transvaginal scan, as per your healthcare provider's guidance.
- Wear Comfortable Clothing: Choose loose-fitting clothes that are easy to remove or adjust, especially around your abdomen.
- Arrive Early: Plan to arrive ahead of time to complete any paperwork and to relax before the scan.
- Bring Emotional Support: Consider bringing a partner, friend, or family member for comfort and reassurance.
- Prepare for the Duration and Results: Expect the scan to take 15-30 minutes. At Docscan your report would be provided to you immediately post the scan is completed. The radiologist will discuss your scan findings with you and answer any queries that you may have.
Questions to Ask Before Your Scan
Before your early pregnancy scan, it can be helpful to ask a few important questions to ensure you understand the procedure and what to expect.
- What Type of Scan Will It Be?
Will it be a transabdominal scan or a transvaginal scan? Understanding the type of scan will help you prepare accordingly, as the instructions for each may differ (e.g., drinking water or having a full bladder). - Do I Need to Do Anything Special Before the Scan?
Are there any specific instructions I need to follow, such as drinking water, fasting, or emptying my bladder before the scan? - What Will the Scan Be Used to Check?
What should I expect to see during the scan? Will it confirm the pregnancy, detect the fetal heartbeat, check for any abnormalities, or help estimate the due date? - How Long Will the Scan Take?
How much time should I allocate for the scan? Understanding the duration can help you plan your schedule and reduce anxiety. - When Will I Get the Results?
Will I get the results immediately after the scan, or will I need to wait for a follow-up appointment or call to discuss the findings?
These questions will help you feel more prepared and informed going into your early pregnancy scan.

Understanding Early Pregnancy Scan Reports
Understanding your early pregnancy scan report can sometimes be confusing, but knowing what to look for can help ease your mind.
Here are some key points that may appear in your report:
Key Components of the Report
- Gestational Sac
The first thing doctors will check for is the gestational sac. It's a fluid-filled space that surrounds the developing embryo. A visible gestational sac is a good sign of an early pregnancy. - Yolk Sac
The yolk sac provides nutrients to the developing embryo before the placenta forms. If a yolk sac is visible, it’s a sign of a healthy early pregnancy. - Fetal Pole
The fetal pole is the early sign of a developing embryo, which will eventually become the baby. Seeing the fetal pole around 6 weeks is a good sign that the pregnancy is progressing well. - Fetal Heartbeat
The fetal heartbeat is often detected by ultrasound after about 6 weeks. Seeing a heartbeat is a reassuring sign that the pregnancy is viable (the baby is developing as expected). - Crown-Rump Length (CRL)
The CRL measures the length of the embryo from head to bottom, helping to estimate how far along the pregnancy is. This measurement helps determine the due date and whether the baby is growing at a normal rate. - Multiple Pregnancies (If Applicable)
If you're carrying twins or more, the scan may show more than one gestational sac, fetal pole, or heartbeat. The report will mention if there are multiples, which means you’re carrying more than one baby. - Subchorionic Hemorrhage or Bleeding
This refers to a small amount of bleeding or clotting near the pregnancy. Sometimes, light bleeding is common and may not be concerning, but it’s important to follow up with your doctor if it’s mentioned in the report.
Benefits of Early Pregnancy Scans
Early pregnancy scans offer several important benefits that can provide reassurance and valuable information during the early stages of pregnancy. Here are the key advantages:
- Confirms the Pregnancy
An early scan confirms whether you're pregnant and ensures the pregnancy is located inside the uterus, ruling out the possibility of an ectopic pregnancy (where the pregnancy occurs outside the uterus). - Accurately Estimates the Due Date
By measuring the gestational sac or embryo, the early scan helps determine the exact gestational age, providing a more accurate estimate of your baby’s due date. - Detects the Fetal Heartbeat
Around 6 weeks, the scan can detect the fetal heartbeat, providing reassurance that the pregnancy is progressing normally and that the baby is developing as expected. - Identifies Multiple Pregnancies
If you're carrying twins or more, an early scan can detect multiple sacs or heartbeats, helping to ensure you receive the right care and monitoring. - Monitors Early Development
The scan provides an early look at the development of the baby, helping to identify any potential issues, such as abnormal growth or structural concerns, that may require attention. - Helps Detect Signs of Miscarriage
Suppose there are signs of a miscarriage, such as an empty sac or no visible fetal heartbeat. In that case, the scan can identify them early, allowing for proper medical guidance and decision-making.
