Ramzi Theory for gender?

Today I am getting a regular transabdominal ultrasound and was wondering what I should look for to see if my child is a boy or girl according to the ramzi theory? It’s going to be administered through planned parenthood , so the nurse might not be familiar with the Ramzi Theory if i were to ask her flat out.

EDIT: And I am aware that isn’t accurate for many. I meant just to do it for fun. I will find out for sure what the gender is when I am far along enough of course.
