What type of ultrasound is done at 8 weeks?
Your first ultrasound is called the “dating” or “viability” ultrasound. It’s typically done between 7 and 8 weeks to verify your due date, to look for a fetal heartbeat, and to measure the length of the baby from “crown to rump.” At this ultrasound, you’ll also learn whether you’re having one baby, twins, or more!
What can you see at 8 week scan?

Are 8 week ultrasounds accurate?
How accurate is the ultrasound examination? Ultrasounds performed during the first 12 weeks of pregnancy are generally within 5 days of accuracy. The most accurate time is between 8 and 11 weeks gestation. This is because the baby is growing so quickly that there is a big difference in size from week to week.
Is no heartbeat at 8 weeks normal?
Why you might not hear baby’s heartbeat You might not be able to hear a baby’s heartbeat at your first ultrasound. Most commonly, this is because it’s too early in the pregnancy. This doesn’t necessarily mean there’s a problem. Your doctor may recommend you schedule another ultrasound 1 to 2 weeks later.
