What is the ‘nub’ on an ultrasound scan?
Ultrasound scans between 12-15 weeks with a profile view can be analysed by the angle and shape of the nub. External gender development for both male and female start the same. Between gestation weeks 7-9 the ‘nub’ is visible and looks identical. The correct term for the ‘nub’ is genital tubercle.
What does the girl ultrasound Gallery Show Me?
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.
Can a nub be seen at 11 weeks?
Some other sites will predict, its down to personal choice if you decide to go ahead, just always have in mind that the nub at 11 weeks looks pretty similar to a girl nub in its 12th week, so the prediction just isn’t accurate enough.

What angle should a girl nub image at 12 weeks?
Here we must look at the angle, a girl nub will image between a 10 and 29 degree angle. Clear parallel girl nubs. The girl nubs seen here are between 12-12.5 weeks in gestation and they have an angle of less than 30 degrees. The bladder is drawn through to the tip of the nub and shows no rise. The tip of the nub is also pointing down.
