Early Fetal Heartbeat Detection: When and How It’s Found

A fetal heartbeat can often be detected as early as 5 to 6 weeks of gestation via transvaginal ultrasound. This method provides the earliest view because the probe is placed closer to the uterus.

With a standard transabdominal ultrasound (over the belly), the heartbeat is typically visible starting around 6 to 8 weeks as the embryo grows.

Keep in mind that gestational age dating can vary slightly based on individual factors (e.g., irregular cycles, uncertain last menstrual period). Every pregnancy is unique, and detection timing may differ. If you have questions or concerns, always consult your healthcare provider for personalized guidance.
