Ramzi theory... 7 week ultrasound after ivf... Please please respond!

Hey ladies.... I put my baby's 12 week 6 day pic up, but no nub, so it was hard to tell. I just read about ramzi theory.... If placenta is to the left of baby, girl.... Right of the baby, it's a boy. I'm sure most of u ladies are familiar with this theory. At first I thought it meant based on placement of baby inside the placenta... But I guess not. It's the placenta placement in relation to the baby. Anyway.... Here is my pic. You'll notice it says baby A.... My precious baby B was called home to heaven.
