I found out at 15 week with a 3D ultrasound
I found out in 19weeks 5 days
You won't find out at 13w. Baby is still far too small. You can tell on us from 15w, but it is more accurate if you wait until 19/20w to find out. I was 19+4 when I found out, then had another US at 24+3 to confirm
Im not expecting to find out till my next sono but wishful thinking lol im only gonna be 13 weeks
I found out bang on 16 weeks :-)
I found out at 19+3 , more accurate
