Nub theory?? Gender prediction.

Jenn

Just wondering if anyone has heard of the 'nub theory' for gender predictions? And if so, has anyone had any success/accuracy in predicting their babies sex this way? I am going for a twelve week scan next week and just curious if anyone has had any success with this theory this early on in their pregnancy...

If you don't know what it is you can google the nub theory for gender prediction 😀
