For many women who conceive through IVF, the scan room is the place where hope meets nerves. You may have waited years for this picture on a screen, and you may also be holding your breath until the doctor speaks. That mix of excitement and fear is very common. Knowing what each scan is for, and what the doctor is looking at, can make the room feel less like an exam and more like a visit with someone on your side.
The Short Answer
What to Know
A pregnancy has several scans over time, and each one answers a different question: is the pregnancy in the right place, how old is it, are there any early signs to screen for, how is the baby's body developing, and how is the baby growing. Scans do not need to be feared, and your doctor will tell you the schedule that suits your pregnancy.
मराठीत थोडक्यात: गरोदरपणात अनेक स्कॅन होतात आणि प्रत्येकाचा हेतू वेगळा असतो: गर्भ योग्य जागी आहे का, किती दिवसांचा आहे, सुरुवातीच्या तपासणीत काही संकेत आहेत का, बाळाची वाढ कशी होत आहे. स्कॅनची भीती बाळगण्याची गरज नाही. तुमच्या गरोदरपणासाठी योग्य वेळापत्रक डॉक्टर सांगतील.
हिंदी में संक्षेप: गर्भावस्था में कई स्कैन होते हैं और हर स्कैन का मक़सद अलग होता है: गर्भ सही जगह है या नहीं, कितने समय का है, शुरुआती जाँच में कोई संकेत है या नहीं, और बच्चे का विकास कैसा है। स्कैन से डरने की ज़रूरत नहीं है। आपके लिए सही कार्यक्रम डॉक्टर बताएँगे।
The Scans at a Glance
| Scan | Roughly when | What it mainly checks |
|---|---|---|
| Early confirmation scan | Soon after a positive test, as your doctor advises | Whether the pregnancy is in the womb, and whether a heartbeat can be seen when the time is right |
| Dating scan | Early in pregnancy | The age of the pregnancy and the expected due date |
| First screening scan | At the end of the first trimester | Early development, and, with blood tests, a screening estimate of certain chromosome conditions |
| Detailed anomaly scan | Around the middle of pregnancy | The baby's organs and body structure, the placenta and the fluid around the baby |
| Growth scans | Later in pregnancy, as advised | How the baby is growing, the fluid, the placenta and the baby's position |
| Extra scans | Only if needed | Follow-up for a particular concern, such as twins, bleeding or a growth question |
The exact timing and number differ from woman to woman. Your doctor will tell you what is suitable, and you should follow that plan. Women with IVF pregnancies often have an earlier first scan, because both you and your doctor want to confirm that the pregnancy is in the right place. If you are expecting twins, the schedule may be different. See twin pregnancy after IVF.
The Early Confirmation Scan
After the positive blood test, usually the first scan is done through the vagina, because it gives a clearer view in early pregnancy. Do not worry, this is a standard way of scanning at this stage. It checks whether the pregnancy is inside the womb and how many sacs there are. As the days pass, it may also show the early heartbeat.
If the scan is done very early, you may see only a small sac, and the doctor may ask you to come back for another scan after a short interval, instead of giving a final answer at once. This is normal, and it does not always mean a problem. Our guide on beta hCG explains how blood tests fit with the first scan.
If you have pain or bleeding, please tell your doctor, who may scan sooner. Read about ectopic pregnancy warning signs and blighted ovum and missed miscarriage if you want to understand the concerns doctors keep in mind.
The Dating Scan
This scan measures the baby to estimate how far along the pregnancy is and to give an expected due date. After IVF, the date of embryo transfer already gives a very reliable starting point, and your doctor will use it together with the scan.
The First Screening Scan
At the end of the first trimester, a screening scan looks at the baby's early development and measures a small fluid space at the back of the baby's neck. Together with a blood test and your age, this gives a screening estimate, which means a likelihood and not a diagnosis.
A screening result that is "higher risk" does not mean that the baby is affected. It means that your doctor may discuss further options. Please talk calmly with your doctor about what the result means, and what you would like to do. Our article on genetic testing and PGT explains the difference between screening and testing in general.
The Detailed Anomaly Scan
Around the middle of pregnancy, a more detailed scan looks closely at the baby's head, spine, heart, face, abdomen, limbs, the placenta and the fluid around the baby. It takes longer than other scans, and sometimes the baby's position makes some views difficult, so the sonologist may ask you to walk around or to return for a repeat view. This is common.
Most detailed scans show a baby who is developing as expected. If something needs more attention, your doctor will explain what was seen and what the next step is, which may include another scan or a specialist review.
In India, the law does not allow doctors to tell you the baby's sex during a scan, and this is to prevent sex selection. Please do not ask the sonologist, and be cautious about anyone who offers to tell you. Our article on baby gender and Indian law explains this in more detail.
Growth Scans
Later in pregnancy, your doctor may advise one or more scans to check the baby's growth, the amount of fluid, the position of the placenta and how the baby is lying. These are advised more often when there is a particular reason, such as twins, diabetes in pregnancy, high blood pressure, or earlier concerns. If you are one of them, our guides on gestational diabetes and is pregnancy after IVF automatically high-risk explain how care is planned.
Worth Remembering
Worth remembering:
A scan is a snapshot of one moment. It answers specific questions, and it can sometimes leave a question open, which is why doctors repeat scans. An open question is not the same as a problem, and your doctor will tell you honestly what is known and what is not.
Are Scans Safe?
Ultrasound uses sound waves, not radiation, and it has been used in pregnancy for many years. Scans are done when there is a medical reason, and your doctor will advise the number that is right for you. Please avoid getting extra scans only for souvenirs or entertainment, and avoid unregulated scan centres. If you have any worry about safety, ask your doctor.
Coping With Scan Anxiety
After infertility, many women feel that each scan is a test they might fail. Some women cannot sleep the night before. Some avoid telling anyone until the scan is done. This is very understandable. A few things can help.
- Take someone with you — Your partner, your mother or a friend can listen and ask questions when you are too nervous.
- Write your questions down — It is easy to forget them in the moment.
- Ask the doctor to explain as they go — Silence during a scan is usually concentration, not bad news.
- Plan something gentle afterwards — A short walk or a quiet meal helps the nerves settle.
- Be honest about how you feel — Tell your doctor that you are anxious. They have heard it many times.

Questions to Ask at a Scan
You do not need to understand every term, but a short list of questions helps.
- Is the pregnancy where it should be?
- Can you explain what I am seeing on the screen?
- Is everything as expected for this stage?
- When is my next scan, and what will it check?
- Is there anything I should watch for before then?
- Do I need any blood tests along with this scan?
Myths and Facts
| Myth | Fact |
|---|---|
| "No heartbeat at the first scan means a loss" | Very early scans may be too soon to see a heartbeat, and a repeat scan is often needed. |
| "More scans mean better care" | Scans are done for medical reasons, and extra scans without a reason add worry, not safety. |
| "A normal scan guarantees a healthy baby" | Scans check many things, but they cannot detect everything. Your doctor will explain the limits. |
| "A screening result is a diagnosis" | A screening result is a likelihood, and further steps are discussed before any decision. |
| "The scan can tell the baby's sex" | The doctor is not allowed to reveal the baby's sex in India. |
Warning Signs: When to Call Your Doctor Between Scans
Contact your doctor promptly if you have:
- Heavy vaginal bleeding, or bleeding with clots
- Severe or increasing abdominal pain
- Fever or chills
- Fainting or severe dizziness
- Leaking fluid from the vagina
- A severe headache, or changes in your vision
- Fewer baby movements than usual, when you are at the stage of feeling them
Please do not wait for your next scheduled scan.
When to Speak to Your Doctor
Speak to your doctor if you are worried about a scan result, if you did not understand what you were told, if you have had losses before and feel anxious about each visit, or if you notice any of the warning signs above. Please ask for the findings to be explained in plain words, and ask for a copy of the report. If the first scan was unclear, a repeat is often the most reassuring step.
A good scan visit leaves you knowing what was checked, what was seen, and what happens next.
