Placenta location

So I read something interesting... 97.2% of boys had their placenta on the right side of the uterus. 97.5% of girls had their placenta on the left side of the uterus. So for those of you who had an ultrasound at 6weeks or later see if this works for you an share your result. Unfortunately I never had an early ultra sound to see if this is at all accurate but I would love to see if it's true for others(:
