Ramzi theory??

I've heard that if the ultrasound is transvaginal, then if the baby is to the left, it will be a girl. If its to the right, it will be a boy. If it's a normal ultrasound, then it's opposite. Is that true? If it's not will someone Ramzi my baby? 
The image is TRANSVAGINAL. It's measuring at 7w1d.
