Once you hit 5 months pregnant you will have your normal health ultrasound. At the time of your ultrasound if they can see the baby's gender then they will ask if you want to know or not. But if the baby is hiding. They don't try to hard to look. You can make a separate apt for a gender reveal 16 weeks plus but your insurance might not cover it.
With my son I got a harmony test done at 7 weeks and found out the gender within 2 weeks. With This pregnancy didn't find out I was pregnant until 10 weeks and found out at 12 weeks I was having a girl through the panorama test.
They usually do the ultrasound anywheres for 16 to 20 weeks to determine the gender. I can't wait to find out what I am having and I will be 10 weeks on Sunday. So sometime in November for me.
In Australia they do the gender reveal at 19-20 weeks...so with my first I found out at 21 weeks :/ with my second I was impatient and had an ultrasound at 12 weeks and just asked while I was there what they thought Bub might be.... Plus you can always have fun doing midwives tales but they are not accurate
You can do a harmony test from ten weeks onwards or you can find out at 16 weeks onwards via ultrasound.
At about 16 weeks, I do believe you can find out via ultrasound.
