Gender Prediction: Old Wives Tales & Ramzi Method. (True or False???)

The Old Wives' Tales
These were my pregnancy symptoms before 16 weeks.

And it turned out to be a GIRL!

Dr Ramzi's Method
Have you heard of the Ramzi's Method on Baby Gender Prediction?

Ramzi's Method: Find Out the Sex of Your Baby at 1st Ultrasound

Here's a short breakdown/explanation of the Ramzi Method:

In using this data, Dr. Ramzi Ismail concluded that at six weeks gestation, 97.2% of the male fetuses had a placenta or chorionic villi on the right side of the uterus. When it came to female fetuses, there were 97.5% of the chorionic villi or placenta on the left side of the uterus.

PS: Do not confuse the "left" and "right" of the ultrasound scan. By looking at your baby's ultrasound scan, what you see on the left, is actually on the right side of your uterus. And what you see on the right side of the ultrasound scan, is actually on the left side of your uterus.
Still confused? Place the ultrasound scan on your abdomen, facing out.

So, this is my first ultrasound scan at almost 6 weeks gestation. 

The placenta seems to be more to the left side (right side of the uterus), so according to the Ramzi's method, I should be having a Boy. BUT, I ended up having a Girl!

So the Ramzi's gender prediction method isn't accurate for me, perhaps my baby is among the 2.5%, since the accuracy of Ramzi's method isn't 100%.
