Gender Ultrasound at 17 weeks

Samara
How many moms already know what they are having? I'm 17 weeks and I am going to have an ultrasound to determine the sex this evening!!! But I think it may be a little too early!! I have my next doc appointment on Dec 2 and ultrasound that day as well but I just can't wait!!! Do you think 17 weeks would be too early? I really want a girl 💞
