When do you all find out gender?

Maggi

We are almost 13 weeks and our doctor did not give us the option for the blood test to determine gender. So we are finding out through ultrasound. My doctor said our next one will be around 19 weeks (which is march 15th because they only do them on tuesdays) but we had planned to do a gender reveal/surprise 50th birthday party for my mother in law on March 19th. I know we will be pushing it if the baby is uncooperative that day. So I am thinking about paying for a 3d or 4d ultrasound to check through a place in my area. But I don't know when to schedule it for! I was hoping for 16/17 weeks, but I'm not sure if thats too early.

When are you having yours done? I am so anxious to find out!!
