How early did you find out gender?

What is the earliest you have found out the gender of your baby, with ultrasound not by the blood tests?

I was 15wks with my first and 16wks with my second. I am high risk and see the specialists, I see them at 13wks with this one and hoping we can get a good peek. I'll see them again around 16wks. How early did you find out?
