Ultrasound Q

[Mehrunisa]

Hi

What is earliest you can have an ultrasound for gender determination and where would you be able to go for that? I am from Canada and here ultraosunds are after 20 weeks where I live and I am just gathering info before I get pregnant.
Thanks

Different hospitals do it at different times. Here It's between 18-22 weeks.

You can ask for a nub shot at your nuchal scan. This is not a definitive gender determination...but it's fun to guess :)
