Can You Tell at the 12-Week Scan?
Posted 17 Oct 2026
Plenty of mums wonder about baby’s sex around the 12-week mark. Here’s a calm, no-pressure look at the folklore and the fun of guessing.
By twelve weeks many parents start wondering whether anyone can tell if it’s a boy or a girl. The dating scan is mainly about checking dates and wellbeing, not announcing sex, yet the curiosity is completely natural.
Online you will find old wives’ tales and the well-known nub theory that some people enjoy applying to early pictures. These ideas are shared for entertainment and light-hearted guessing rather than as firm answers.
Every pregnancy looks a little different on the screen, and positions change from moment to moment. That is why most families treat early peeks as a bit of fun while they wait for clearer information later on.
If you like keeping a bump journal or comparing notes with friends, jotting down your twelve-week thoughts can become a sweet keepsake. There is no rush and no right or wrong way to feel about it.
However you choose to mark the milestone, enjoy the quiet excitement of this stage. The weeks ahead will bring their own surprises, and the story of your baby is already unfolding beautifully.
