What Does a Baby Girl Look Like on Ultrasound?

The girl ultrasound gallery is designed to show you what a baby girl looks like on ultrasound photos from various weeks of pregnancy. You'll notice that what you see varies a lot by the number of weeks of gestation. Each week in pregnancy can look slightly different. This can be due to the baby's development, the weight of the mother, the position of the baby, and the skill of the ultrasound technician, for example.

There are a lot of theories about what the ultrasound technician is looking for in a girl ultrasound. Is it true that three lines in ultrasound means girl? This is often called the "hamburger sign." Some technicians look for two lines. And yet others go by the old adage, no penis means it's a girl.
