Anyone waiting til birth to find out the gender?

De

I had my 20 week scan on Monday where I was expecting to find out whether the baby is a boy or girl. However, the little one had other ideas so the doctor was unable to see! Following that, I've decided to wait til the birth for a surprise, much to the discontent of my in laws. Anyone else waiting til the birth? It's gonna be a challenge because I'm usually a very impatient person!
