How to do a seven-month fetal B-ultrasound?
Under normal circumstances, pregnant women will undergo fetal B-ultrasound examination when they are 7 months pregnant.

During a B-ultrasound examination, the doctor will use a special probe to illuminate the fetus through the abdomen and display the image on the screen.
Common charts for fetal gender identification

2. Genital map: In the B-ultrasound image, the genitals of a baby boy will form a long strip, while the genitals of a baby girl will form a T shape.
3. Circumference chart: The head circumference, abdominal circumference, femur length and ventricular width of baby boys are usually larger than those of baby girls.
