First Trimester Scans: Importance, Procedure, and What to Expect

What Are First Trimester Scans?

First trimester scans are special ultrasound tests done during the first 12 to 14 weeks of pregnancy. These early pregnancy ultrasounds help doctors check the health and growth of the baby. Usually, a first trimester scan is the first detailed look at your baby inside the womb. Because these scans are safe and painless, many doctors recommend them for all pregnant women.

Why Are First Trimester Scans Important?

First trimester scans play a key role in early pregnancy care. For example, they help confirm the pregnancy and check if the baby is growing well. In addition, these scans can spot early problems, which means doctors can act quickly if needed. According to the World Health Organization (WHO), early scans improve pregnancy outcomes by finding issues sooner.

  • Confirm the pregnancy is inside the womb
  • Check the baby’s heartbeat
  • Measure the baby’s size and age
  • Detect twins or more babies
  • Spot early signs of problems
  • When Are First Trimester Scans Done?

    Doctors usually suggest a first trimester scan between 6 and 14 weeks of pregnancy. However, the most common time is around 8 to 12 weeks. Sometimes, your doctor may ask for an earlier scan if you have pain, bleeding, or other concerns. In many clinics, you can book a first trimester scan in your city or area by calling ahead.

    How Are First Trimester Scans Performed?

    First trimester ultrasound procedures are simple and safe. Most often, the scan is done in two ways:

  • Transabdominal scan: The doctor moves a small device over your belly. You may need a full bladder for clearer pictures.
  • Transvaginal scan: The doctor gently places a thin device inside the vagina. This gives a closer view, especially in early weeks.
  • During the scan, you will lie on a bed. The doctor will use a cool gel to help the device glide smoothly. The whole process takes about 15 to 30 minutes. While you may feel a little pressure, the scan should not hurt.

    What Do First Trimester Scans Detect?

    First trimester scans can find many important details about your pregnancy. For instance, they can:

  • Confirm the baby’s heartbeat
  • Measure the baby’s length (crown-rump length)
  • Check the baby’s age and due date
  • Detect twins or triplets
  • Spot early signs of miscarriage
  • Find some birth defects early
  • Check the mother’s uterus and ovaries
  • Because these scans give so much information, they are a key part of early pregnancy care.

    How to Prepare for a First Trimester Scan

    Getting ready for a first trimester scan is easy. Still, a few steps can help:

  • Drink water before the scan if your doctor asks for a full bladder
  • Wear loose, comfortable clothes
  • Bring your medical records or previous scan reports
  • Arrive a little early to relax before the test
  • Most clinics will explain what you need to do before your appointment. If you have questions, ask your doctor or nurse for help.

    Safety and Risks

    First trimester scans are very safe for both mother and baby. In fact, ultrasound uses sound waves, not radiation, to make pictures. According to the Centers for Disease Control and Prevention (CDC), there are no known risks when scans are done by trained professionals. However, scans should only be done when needed and not just for fun.
