The earliest time we can assess the babys sex is at 12 weeks gestation/pregnancy: We can tell the sex of the baby at the 12 week scan by assessing the direction of the nub. This is something that can be identified on babies at this stage and if it points vertically then it is likely to be a boy.

What is the 12 week rule?

There is a common myth amongst many pregnant couples that the so called 12-week rule must be adhered to when announcing a new pregnancy. This means that a couple should keep their pregnancy a secret until they get to the 12 week or three-month mark – the point where a pregnancy announcement is viewed as safe.
