7 Week Ultrasound: Heartbeat Detection and What to Expect
At 7 weeks, your first ultrasound may detect your baby's heartbeat. Learn about reasons for scanning, dating accuracy, and what the sonographer checks.
At around 7 weeks of pregnancy, it is reasonably common for women to have their first ultrasound. This can be for many reasons, but the most common is to confirm pregnancy and check that the embryo is viable and "everything's ok." The 7 week ultrasound is a special milestone as this is when a heartbeat can often be detected.
Reasons for a 7 Week Ultrasound
- Confirm the presence of one or more embryos and gestational sacs
- Assess the gestational age (also known as a "dating scan")
- Identify the cause and source of blood loss if a mother has been experiencing bleeding
- Confirm the presence of a heartbeat
- Check the size of the embryo and ensure the baby is the right size for gestational age
- Perform a general check of the uterus, fallopian tubes, and ovaries
- Ensure the embryo has implanted within the uterus and rule out ectopic pregnancy
- Clarify dates when a mother is unsure about her last normal menstrual period (LNMP)
