During my pregnancy, curiosity got the best of me; I couldn’t wait to know my baby’s gender. That’s when I stumbled across something called “nub theory.” What started as a late-night search quickly turned into a deep fascination. I found myself analyzing ultrasound images, comparing angles, and learning everything I could about this early gender prediction method. What began as simple curiosity soon grew into a true passion. Over the past eight years, I’ve continued to study nub theory, diving deeper into its nuances and accuracy. I’ve spent countless hours educating myself, reviewing images, and staying up to date with evolving insights. What once helped me during my own pregnancy has now become something I genuinely love: learning, refining my skills, and sharing that knowledge with others who are just as curious as I once was. I've combined my passion and experience to create The Nub Hub.
