My private place I go to won't do gender scans till at least 15 weeks to make sure the genitals are completely formed, and even then it can still be not quite accurate.

I had a private ultrasound done at 13 weeks and it was correct.

I had the chromosomal blood test like @theinkedmommy and found out at 12 weeks. Depends on your age or insurance of it's covered or not.

I think the 3D ones are probably more accurate. If yours is specifically someone for gender reveals then I suppose it'll be fine. I really have no experience of it so I can't say! I wish you well though 😘

@miicat, I made an app with a private ultrasound place that does nothing but gender reveals and is this Saturday which I'll be 14 weeks 1 day, im a little nervous!

I think it is. If you wait longer it's easier to make it accurate. Some doctors won't even tell you if they're not 100% sure.
