Gender ultrasound question

Lauren
How many of you ladies found out the gender before 20 weeks? We have a place out in town that can do it at 14 weeks and on and we're considering getting it done between 15-16 weeks. I'm 13 weeks now. Did anyone have luck finding out then? Was it accurate? Trying to decide if it's worth it or if we should (impatiently) wait till 20 weeks. Thanks ladies!
