Okay, just wondering if any of you were sure you knew if you were having a boy or girl, before you had the scan to confirm, or before you had the baby and were you right?

With my last pregnancy which ended in a miscarriage, I was absolutely certain it was going to be a boy and afterwards dr confirmed it was a boy.
This time I'm absolutely certain again about the sex, but won't be finding out till birth. I'm curious if I'll be right this time...
