Want an early hint at your baby’s gender? Our Nub Theory prediction offers a fast and exciting way to find out—often weeks before your official scan.

By studying your 12–14 week ultrasound, we look at the angle of the “nub” (a small anatomical feature that develops into the genital area) in relation to your baby’s spine. This method can provide a strong early indication of whether you may be expecting a boy or a girl.

Each scan is carefully reviewed for positioning, clarity, and accuracy to give you the most reliable prediction possible.

What’s included:

  • Personalized gender prediction within 24 hours
  • Careful review of your ultrasound image
  • Confidence rating based on image quality
  • Simple explanation of how we reached your result

For best results, submit a clear side-profile ultrasound taken between 12 and 14 weeks. While Nub Theory can be very accurate under the right conditions, it’s intended as an early prediction and not a medical confirmation.

Upload your ultrasound today and discover your baby’s possible gender sooner!
