Ramzi been wrong?!

Kay
Hey all! I'm almost 12 weeks now and in that 1 week wait for the genetic test to come back  where we get to find out the gender as well as the presence of certain conditions! 
I sent in my ramzi thing a few weeks back and it came back and said boy! The Chinese gender chart also says boy....I was just wondering if anyone has had Ramzi be wrong?! I would be so happy with either gender, I'm just curious!
