Early Pregnancy Ultrasound in Korea: When Can You See the Baby?

What you'll see at 5, 6, 7 and 8 weeks

Seeing your baby for the first time on an ultrasound is a special moment. In Korea, ultrasounds are a routine part of early pregnancy care. But what can you expect to see — and when? Here's a week-by-week guide to early pregnancy scans.

How Pregnancy Weeks Are Counted

Pregnancy is dated from the first day of your last menstrual period, so at "4 weeks pregnant" conception occurred about two weeks earlier.

What You May See

• Around 4.5–5 weeks: a small gestational sac in the uterus
• Around 5.5 weeks: the yolk sac, which nourishes the early embryo
• Around 6 weeks: a tiny embryo and often a flickering heartbeat
• 7–8 weeks: a clearer embryo and a stronger heartbeat
• 11–13 weeks: a more baby-like shape; screening scans may be offered

Timing varies, especially if your cycles are irregular.

What Early Scans Check

• That the pregnancy is in the uterus, not ectopic
• The number of embryos
• The presence of a heartbeat
• Your due date, based on the embryo's size

Transvaginal vs Abdominal

In early pregnancy, transvaginal ultrasound gives the clearest view. It's safe for you and the baby.

"It's Too Early to See" — What That Means

If the scan is done very early, the doctor may not see everything yet. You may be asked to return in 1–2 weeks or have blood hCG tests. This is common and doesn't necessarily mean something is wrong.

Seek Care Promptly If

You have heavy bleeding, severe pain or feel faint.
