Nervous to find out gender

Okay so since I found out I was pregnant all I have wanted was to know the gender! Hubby and I both really want a boy, I want a girl too I just always wanted the boy to be older. Now my gender scan is a week away and I am SO nervous!!! I want to know but I'm scared if it's not what we want I won't be excited and I might even cry... and I feel like since I want boy so bad it will be a girl just because that's what always seems to happen to people.
