They told me with blood test at 12w
I went to an ultrasound clinic at 16 weeks and found out. They say sometimes they can tell at 13 weeks but don't guarantee it until 16 weeks. At 16 weeks if they can't u can go back for free
My fren found out between 13 -14 weeks with 3d
They can normally detect it around 14-15 weeks. At your doctor they won't tell you until 20 weeks. So you have to find a place that specializes in gender sneak peaks!
