Why Pregnancy Myths Refuse to Disappear

Pregnancy is one of the most common human experiences—and one of the most misunderstood. Despite millions of people giving birth every year, pregnancy has long existed behind a veil of privacy, quiet tradition, and, at times, shame. For generations, many people navigated it silently, sharing details only within families or not at all. That secrecy created fertile ground for myths, folklore, and “old wives’ tales” to flourish.

Today, pregnancy is more visible than ever. Social media has opened the door for parents—especially mothers—to share symptoms, fears, milestones, and realities in real time. And yet, a surprising number of long-standing pregnancy myths remain firmly believed, according to a recent survey by Talker Research.

What the Survey Says About Pregnancy Beliefs

Talker Research surveyed 2,000 parents-to-be, including 250 people who were pregnant at the time and another 250 who were actively trying to conceive. The results suggest that even in an age of medical testing and instant information, many expectant parents still hold onto ideas that aren’t supported by science.

Nearly three in ten respondents believed that experiencing heartburn during pregnancy means a baby will be born with a full head of hair. While one small study has suggested a possible correlation, there is no strong scientific evidence proving this claim. Similarly, 21% of respondents believed that eating spicy food can induce labor—a popular belief that has not been supported by scientific research.

Other myths appear rooted in ancient traditions. One in five respondents said they believed the phase of the moon at conception could influence a baby’s sex, an idea that has been passed down through generations across cultures.

Guessing Baby’s Sex: Myths vs. Reality

Beliefs around predicting a baby’s sex remain especially persistent. Many respondents reported believing that physical appearance during pregnancy offers clues—such as the idea that carrying a girl will leave a mother looking tired, while carrying a boy brings a noticeable glow.

The survey results told a different story. More parents who went on to have girls reported glowing skin than those who had boys, directly contradicting the popular myth.

The same pattern emerged with the belief that “carrying low” means a baby is a boy. While 14% of respondents who had boys reported carrying low, 12% of those who had girls said the same—suggesting that this supposed signal offers little predictive value.

The Family Lore That Gets Passed Down

Beyond commonly known myths, the survey also included open-ended responses that revealed the deeply personal folklore shared within families. Some of these beliefs were charming, others puzzling, and many uniquely specific.

“If we dream about fish, someone is pregnant in our family,” one respondent shared. Another wrote, “Pregnant women shouldn’t look at roadkill.”

These stories highlight how pregnancy myths are often less about accuracy and more about tradition, connection, and shared understanding.

Why Pregnancy Myths Persist

Pregnancy is an intensely personal experience filled with unknowns. Even with modern medicine, many aspects—how labor will unfold, how the baby will adapt, what parenthood will feel like—remain beyond anyone’s control. In moments of uncertainty, people naturally search for meaning in small details.

These myths offer something concrete in a process that can feel abstract and overwhelming. They turn bodily sensations and daily observations into narratives, helping expectant parents feel more grounded and connected.

What’s perhaps most surprising is that these beliefs persist despite advances that allow parents to know more than ever before. Blood tests can now reveal a baby’s sex early in pregnancy, sometimes with results delivered straight to an inbox. Yet many parents still enjoy guessing, predicting, and wondering.

And that may be the point.

The Comfort of Belief

Even if pregnancy myths don’t hold up under scientific scrutiny, they serve an emotional purpose. They invite curiosity, encourage mindfulness, and add a sense of play to a time that can otherwise feel heavy with responsibility and worry.

Believing that heartburn might hint at a baby’s hair—or that a glow might signal who you’re carrying—can make the long wait feel lighter. And if those guesses turn out to be wrong, they still become part of the story parents tell about how they imagined their child before they arrived.

So while science can explain pregnancy with increasing precision, there’s still room for wonder. And if a few harmless myths make the journey feel warmer, more connected, or a little less stressful, it’s no surprise they continue to endure.
