What to expect at the NT scan and testing?

Sandra
My appointment is Monday, I'm excited to see my baby again! I'll be 13 weeks 5 days. If they can tell the Gender they would defintly ask me if I want to kno right? My sister will be there but I am having a gender reveal party and I don't want to spoil the surprise plus my bf and I want to find out together. I think if they asked me I would ask them to write it down and put it in an envelope and my bf and I would open it together.do you think that's unrealistic? What can I expect at the ultrasound?
