When Do You Find out the Sex

When Do You Find out the Sexの要点や背景を専門的かつ分かりやすくまとめました。全体像を一目で把握できます。

Around 18 to 22 weeks, you get the “anatomy scan.” This is the classic gender reveal moment. The technician slides a wand over your belly, and suddenly, there it is: a tiny turtle, or a little alien—I mean, a baby.

Here’s the funny part: it’s not always obvious. Babies are stubborn. They cross their legs, turn their backs, or hide behind a hand. You might get a blurry image that looks like a potato.

If the baby is in a bad mood, you walk away with a “maybe next time.” Congratulations, you just lost the game of peek-a-boo.

The “Nub Theory” Rabbit Hole

Before the anatomy scan, the internet goes crazy. Around 12 weeks, you can try the “nub theory.” It’s basically reading a blurry dot. Parents post grainy ultrasound photos in forums, and strangers debate: “That’s totally a boy!” or “No, girl, for sure.”

Spoiler: It’s wrong half the time. But it’s insanely fun to guess. You’ll find yourself zooming in on a pixel. It’s like a Rorschach test, but with more hormones.
