AM I TO OLD FASHIONED?

I know almost everyone like to get their sonogram to find out the of their baby but I never find out until I have my baby, for some reason I love the surprise and feeling I get when the doctor say It's a boy/or girl. I have 5 kids already 2 girls, 3 boys and I am 13 weeks. Do you think I am being to old fashioned by waiting to find out my baby's ?
