You lie on the table, the cool gel touching your belly, and suddenly you see it: a tiny being moving, whose heart is beating – your baby. Many expectant moms describe this moment as overwhelming, as the moment when the pregnancy truly becomes real. At the same time, a thousand questions are swirling in your mind: What will be examined? Is everything okay? What do all these numbers on the screen mean?

The first major ultrasound examination between the 9th and 12th weeks of pregnancy is more than just a medical appointment – it is a milestone. Here you will find out exactly what to expect, which examinations will be performed, and how you can fully enjoy this special moment.

Why the First Ultrasound Examination is So Important

The first basic ultrasound examination typically takes place between the 9th and 12th week of pregnancy. This appointment primarily serves to confirm the pregnancy and collect important basic information. It is the moment when positive test strips and pregnancy symptoms become a visible, living baby.

Your gynecologist will check several crucial points:

  • Implantation in the uterus: It will be checked whether the fertilized egg has implanted correctly in the uterus and that there is no ectopic pregnancy.
  • Heartbeat: The most important moment for many parents – your baby's little heart is already beating strongly, about 120-160 times per minute.
  • Development of the embryo: Your baby has developed from an embryo to a fetus and already shows amazing details.
  • Multiple pregnancy: If you are expecting twins or multiples, this will now be visible.

This examination provides you and your medical team with the assurance that your baby is developing healthily and that everything is proceeding normally.

What You Can See on the Ultrasound Image

At 12 weeks pregnant, your baby is about 5-6 centimeters long – approximately the size of a lime. And although it is still so tiny, you can already see remarkably detailed images on the ultrasound.

Little Wonders Becoming Visible

At this stage, you can already see small fingers and toes on the ultrasound image. Your baby is able to move its arms and legs – sometimes you can even see it turning or bringing its hands to its face. These movements are not yet felt by you, but are clearly visible on the screen.

The head appears proportionally large compared to the body, which is completely normal at this stage. You can see the spine, which looks like a string of pearls, and perhaps even the profile of your baby – a moment that touches many parents particularly deeply.

Important Measurements for the Due Date

During the examination, your doctor will take various measurements:

  • Crown-rump length (CRL): The body length from the head to the bottom is measured.
  • Biparietal diameter (BPD): The diameter of the head gives insight into the development.
  • Amniotic fluid volume: The amount of amniotic fluid is assessed.

These measurements help to precisely determine the gestational week and calculate or correct the expected due date. Sometimes, the ultrasound values differ from your own calculations – this is completely normal and gives you a more accurate date.

The Nuchal Translucency Measurement – An Important Decision

In addition to the basic ultrasound examination, you have the option of having a nuchal translucency measurement (also known as nuchal fold measurement) performed. This examination is optional and is offered between the 11th and 14th week of pregnancy.

What is Measured and Why?

This examination measures the fluid accumulation in the nuchal area of your baby. An increased nuchal translucency can – but does not have to – indicate chromosomal disorders such as Trisomy 21 (Down syndrome). Often, this measurement is combined with a blood test to allow for a more accurate risk assessment.

It is important to know: This examination provides no diagnosis, only a statistical probability. An abnormal value does not automatically mean that something is wrong – and a normal value is not a 100 percent guarantee.

Costs and Decision Guidance

The nuchal translucency measurement is not covered by health insurance and usually needs to be paid privately (approximately 150-250 CHF, depending on the practice). Whether or not to undergo this examination is a very personal decision.

Ask yourself:

  • Do I want more information about potential risks?
  • Would an abnormal finding influence my decisions?
  • Can I cope with uncertainty if the result is borderline?
  • Do I need this information for my peace of mind?

There is no right or wrong – only what feels right for you. Speak openly with your doctor about your thoughts and concerns.

How to Best Prepare for the Appointment

To fully enjoy the first major ultrasound, here are some practical tips:

Practical Preparation

  • Drink enough beforehand: A full bladder can improve the view of the uterus, especially during early ultrasounds. Check with the practice beforehand if this is desired.
  • Wear comfortable clothing: Two-piece outfits are more practical than dresses since you only need to expose your belly.
  • Bring your partner or a trusted person: This moment is emotional, and it’s nice to share it.
  • Plan enough time: Rushing before or after the appointment can dampen the joy.

Emotional Preparation

It’s completely normal to feel nervous. Many women report mixed feelings: anticipation, fear, excitement. Allow yourself to feel all emotions. If you are very anxious, discuss this openly – your medical team can provide additional explanations and reassurance.

Also prepare questions you want to ask. Write them down so you don’t forget anything in the exciting moment:

  • How big is my baby exactly?
  • Is the due date correct?
  • Is the development age-appropriate?
  • Can I take pictures or a video home?
  • Is there anything specific I should pay attention to?

After the Ultrasound: What Comes Next?

After the examination, you will typically receive ultrasound images for your pregnancy journal or album. Many practices now also offer short videos – feel free to ask about this!

The results will be documented in your maternity record. Your doctor will discuss all findings with you and explain what the various values mean. Don’t hesitate to ask questions if something is unclear.

If something unusual is detected during the examination, it does not automatically mean the worst. Further examinations are often required to get a clearer picture. Your medical team will guide you through each step and explain all options.

The Next Ultrasound Appointments

After this first major ultrasound, there will be two more basic ultrasound examinations during the course of the pregnancy:

  • Second ultrasound (19th to 22nd week): Detailed organ examination
  • Third ultrasound (29th to 32nd week): Growth check and position of the baby

Each of these appointments offers you new, fascinating insights into your baby’s development.

Enjoy This Special Moment

The first major ultrasound examination is a milestone on your pregnancy journey. It is the moment when abstract pregnancy symptoms become a visible, moving baby. Don’t be overwhelmed by the medical details – at its core, it’s about seeing your child for the first time.

Take time after the appointment to process the experience. Many women report feeling even more connected to their baby after this ultrasound. The pregnancy becomes real, tangible, wonderful.

Whether you go alone or with company, whether you have the nuchal translucency measurement or not, whether you cry tears of joy or simply stand in silent awe – your way of experiencing this moment is just right. Trust your feelings, ask your questions, and enjoy this first big glimpse of your little wonder.
