The best time to do an initial ultrasound is typically between 7 and 8 weeks of pregnancy.
Here's why this timeframe is optimal:
- Due Date Verification: An early ultrasound helps accurately determine your estimated due date by measuring the baby's crown-to-rump length.
- Fetal Heartbeat Detection: By 7-8 weeks, the fetal heartbeat is usually detectable, confirming a viable pregnancy.
- Determine Number of Fetuses: This ultrasound can reveal if you are pregnant with one baby, twins, or multiples.
- Assess Gestational Age: Measuring the fetus provides a reliable estimate of gestational age.
While other ultrasounds are performed throughout pregnancy for various reasons (anatomy scans, growth monitoring), the 7-8 week ultrasound serves as a crucial initial assessment.
