How does gender prediction work?

[MelliPaige]

What do you use to guess the gender and at how many weeks does the theory work?

There are so many ways everything was wrong for me both times.

I think nub theory is the only real way to predict gender (other than really specific medically-ordered blood tests that aren't generally for predicting gender but for genetic issues, etc.)

Here's a site explaining nub theory: https://www.parentdish.co.uk/2009/06/03/nub-theory-baby-gender-prediction-at-12-weeks/

Also nub theory only works between 12-13 weeks I believe

My first ultrasound will be at about 9 weeks, will it work for me?

I had my first scan just over 9 weeks and could see a girlie nub then, so you might be able to in yours x

They say the nub theory is really unreliable even at 11 weeks so 9 weeks it could really be boy or girl, no matter what the nub looks like (I guess boy nubs only start to rise by 12 weeks is the point).
