Husbands birthday gender ultrasound

Linda

My husband's birthday is next week, I'll be 14 weeks 5 days along. I am contemplating getting a gender ultrasound at a private place and then having the tech put the results in an envelope. I was thinking I could then go pick a baby outfit for each gender and have the cashier check out and wrap the correct one.

Who has had a gender ultrasound this early and was it accurate?

Is this a good gift idea, it's our first little one.
