Can you tell a girl a boy from a b ultrasound single?

I often hear from the mouth of the old man that giving birth to a boy and a girl has been stereotyped very early, for example, a boy is long before two months of pregnancy, and a girl is oval or round, so I thought of a way, I don't know if I can see if I can know if it is a boy or a girl early: it is from the B ultrasound single.

This statement has always been there, and the sooner you see it, the better, but it's not easy to judge. The specific way to see the baby's gender from B-ultrasound alone is:

First: look at the data, if the difference between length and width is more than doubled, the baby boy is more likely. Babies of equal length and width are more likely.

Second: look at the shape, like eggplant or long strips are more likely to be male babies, and round ones are more likely to be female babies. >> B ultra single boy and girl difference.

It can be seen, but it is within the scope of control, and the state is not allowed to do identification.

Is the month enough? Consult a medical professional. How is the male treasure? How is the female treasure? Is it good to have a healthy baby?

That's not obvious, go to the hospital and find someone you know, everything needs a relationship now.

First Khan one. I'm a B-ultrasound doctor. I don't seem to have heard that men and women can be seen according to the list, hehe, whether it is a man or a woman, only the doctor who does B ultrasound knows in his heart.
