What week of pregnancy should a woman have a gender reveal

I had mine at 16 weeks. But you can do it whenever

Whenever you feel like it after you have the gender confirmed.

I did it at my baby shower last weekend. 31 weeks

I found out at 19 weeks and had gender reveal two weeks later

I found gender out at 20 weeks, we did the party that weekend.

My sister had to have 4 ultrasounds and was 30 weeks before they found out because her baby was super stubborn!
