Ultrasound is one of the most important tools used during pregnancy to monitor the health of both the mother and baby. It provides a safe, painless, and non-invasive way to see inside the womb and track fetal development. But many expecting mothers often wonder: when exactly should you get an ultrasound?
At Care Infinity in Patna, our experienced gynecologists and radiologists ensure that every ultrasound is done at the right time and for the right reasons. In this blog, we’ll guide you through the recommended ultrasound schedule during pregnancy and what each scan reveals.
What is a Pregnancy Ultrasound?
A pregnancy ultrasound uses high-frequency sound waves to create images of the growing baby in the womb. It helps confirm the baby’s heartbeat, position, growth, and any potential complications that may arise during pregnancy.
There are two main types of ultrasounds:
Transabdominal ultrasound: The probe is moved across your belly.
Transvaginal ultrasound: A probe is gently inserted into the vagina (usually done early in pregnancy).
Recommended Ultrasound Timeline During Pregnancy
1. Early Pregnancy Scan (6–9 Weeks)
Purpose:
Confirm pregnancy
Check for multiple pregnancies (twins or more)
Detect fetal heartbeat
Rule out ectopic pregnancy
Note: This is usually a transvaginal scan.
2. First Trimester Scan (11–14 Weeks) – NT Scan
Purpose:
Measure nuchal translucency (fluid at the back of the baby’s neck)
Screen for Down syndrome and other chromosomal conditions
Check basic anatomy and gestational age
Estimate due date
This is a key scan for assessing early development.
3. Second Trimester Scan (18–22 Weeks) – Anomaly Scan
Also known as: Level II ultrasound or morphology scan
Purpose:
Detailed check of baby’s organs and structures
Detect any birth defects or abnormalities
Assess placenta position, amniotic fluid, and baby’s growth
Check baby’s sex (if parents wish to know and if allowed)
This is considered the most detailed and important scan during pregnancy.
4. Growth Scan (28–32 Weeks)
Purpose:
Check baby’s growth rate and position
Measure amniotic fluid level
Assess placenta function
Detect intrauterine growth restriction (IUGR)
Growth scans are recommended if there are any concerns about the baby’s development or maternal health issues like high blood pressure or diabetes.
5. Final Scan (36–38 Weeks)
Purpose:
Confirm baby’s position before delivery (head-down or breech)
Check placental maturity
Monitor fluid levels
Plan for delivery method if any complications are expected
Additional Ultrasounds (if needed)
Some women may require more frequent scans if they have:
High-risk pregnancy
Gestational diabetes
Previous pregnancy complications
Bleeding or pain
Twins or multiple babies
Reduced fetal movements
Your doctor at Care Infinity will advise based on your individual needs.
Is Ultrasound Safe During Pregnancy?
Yes. Ultrasounds use sound waves — not radiation — and are considered completely safe when done by trained professionals. At Care Infinity, we follow all safety guidelines to protect both mother and baby.
