first ultrasound and ramzi theory?

Kellie
Hi Ladies, 
I had my first ultrasound today at 6w6d but measuring at 6w1d. The little bean was tiny but you can just see it here being measured (at 0.56cm?) HR was 116bpm is that good for what he/she is measuring at? Anyone know why my little bean is down in the bottom left corner? Haha. Any guesses for the ramzi theory everyone talks about?
