I'm 12 weeks pregnant and am volunteering to have a 3d/4d ultrasound at an ultrasound tech school this Friday. They said that they are allowed to disclose the gender if they are able to see it but I'm wondering if that's even possible that early. I found out at 16 weeks last time but that was with reg ultrasound. Does anyone know if 3d could show sooner? I've read that the genitals are fully formed by 12 weeks so hoping they might be visible :)
