What is an Obstetric Ultrasound (USG Obstetrics Scan)?

An obstetric ultrasound is a painless scan that creates live images of your baby using sound waves — no radiation involved. Depending on the stage of pregnancy, your doctor may suggest a transabdominal scan (transducer moved over the belly) or a transvaginal scan (used mostly in early pregnancy, before 10–12 weeks, when the uterus is still too small to see clearly from the outside).

Through the scan, your doctor can check the baby's heartbeat, position, amniotic fluid level, placenta location, and overall growth — and screen for certain developmental concerns at specific weeks of pregnancy.

How Many Pregnancy Ultrasounds Will I Need?

Most women need 3 to 4 scans across a pregnancy, each timed to check different things. Here's how Femmenest structures them:

If an NT or anomaly scan throws up a finding that needs a closer look, our fetal medicine team follows up with further evaluation, and genetic counseling is offered where the findings warrant it.

Why Choose Femmenest for Your Obstetric Ultrasound?

• Doctor-led, not technician-only. Scans and reports are reviewed by our team — meet the full team — so any concerning finding is flagged and explained the same day, not just printed on a report.
• 18+ years of obstetric and fertility experience. Dr. Aggarwal is Associate Director & Head, Department of IVF & Gynaecology at Max Hospital, Vaishali. Read more about Femmenest.
• Built for high-risk pregnancies too. If your pregnancy needs closer monitoring, our ultrasound protocols connect directly into our high-risk pregnancy care program rather than treating the scan as a one-off.
• Modern digital ultrasound equipment, kept updated for clearer fetal imaging, especially useful for anomaly and Doppler scans.
• Comfortable for first-time and repeat patients alike — most scans take 20–30 minutes, and a partner or family member is welcome in the room for routine scans.

What to Expect During Your Pregnancy Ultrasound Appointment

• Before 10–12 weeks: you may be asked to come with a full bladder for a clearer transabdominal view, or a transvaginal scan may be used instead — your doctor will tell you which applies.
• After 12 weeks: no special preparation is usually needed; wear comfortable, loose clothing.
• During the scan: a warm gel is applied to your abdomen and a handheld transducer is moved over the area. You may feel light pressure, but it shouldn't hurt.
• After the scan: your doctor walks you through the images and findings the same day, and lets you know if any follow-up test or visit is needed as part of your pregnancy check-up schedule.
