First Ultrasound During Pregnancy: When and What Can Be Seen?

Hello! Today, we will discuss an important topic — the first ultrasound during pregnancy. Often, women ask when to do the ultrasound and what can be seen at different stages. Let’s explore when it’s best to schedule your first ultrasound and what you should pay attention to.

When Should You Have Your First Ultrasound During Pregnancy?

The first ultrasound is crucial for confirming early pregnancy. It helps confirm the pregnancy and rule out potential complications. However, it’s important to understand that performing the ultrasound immediately after a missed period might not provide enough information.

• In the early stages (the first day of a missed period), an ultrasound may not show the gestational sac in the uterus, as it needs some time to form.
• The best time for an ultrasound is around 5-6 weeks of pregnancy, when the gestational sac reaches about 3-4 mm, and the scan is more informative.
• At 5-6 weeks, the embryo and its heartbeat can already be detected.

How Is Pregnancy Dating Calculated?

Pregnancy is typically dated from the first day of the last menstrual period. This method is convenient, but it’s important to remember that conception usually occurs in the middle of the cycle, and it can be difficult to pinpoint the exact moment of conception. By the 5-6 week mark, the first signs of the embryo will be visible on ultrasound.

What Can Be Seen on Ultrasound at 5-6 Weeks?

At this stage, the doctor will be able to see:

• The gestational sac within the uterus.
• The embryo's heartbeat, which is an important sign of a developing pregnancy.
• The embryo and its growth.

How to Confirm Pregnancy in the Early Stages?

If you're unsure about your pregnancy, a blood test for beta-hCG can help confirm it in the earliest stages. This test helps verify whether the pregnancy is progressing normally.

• If the beta-hCG level doubles every 48 hours, it indicates that the pregnancy is progressing.
• Once beta-hCG reaches 1500-2000 mIU/ml, you can confidently schedule your ultrasound.

When Should You Schedule an Ultrasound?

If you have no symptoms and your pregnancy is progressing normally, it’s best to wait until the 5-6 week mark. However, if you have concerns, such as abdominal pain or spotting, don’t delay in seeing your doctor. An ultrasound can help rule out or confirm any complications.

How to Prepare for an Ultrasound During Pregnancy?

To ensure that the ultrasound is as informative as possible, follow the doctor’s recommendations:

• Do not drink too much liquid before the procedure.
• Arrive at your ultrasound with a full bladder if a transabdominal scan is required.
• No special preparation is needed for a transvaginal ultrasound.

Conclusion

The first ultrasound is an important milestone for expectant mothers. It helps confirm pregnancy, rule out complications, and establish the gestational age. Don’t worry if your first ultrasound shows only small changes; this is normal, and the doctor may recommend follow-up exams later on.
