10 Pregnancy Myths You Should Stop Believing

  Written by ashleigh s
  Published on October 9th, 2025

Pregnancy is a time filled with excitement, anticipation, and sometimes, a lot of confusion. Along the way, you’ll encounter countless pieces of advice—some helpful, some questionable, and many based on long-standing myths that have been passed down for generations. While these myths might seem harmless, they can cause unnecessary worry or lead to unhelpful expectations. To help you separate fact from fiction, here are 10 common pregnancy myths you should stop believing.

1. You’re Eating for Two

While it’s true that your nutritional needs increase during pregnancy, eating for two doesn’t mean you need to double your food intake. Most women only need an additional 300 calories per day during the second and third trimesters. Overeating can lead to excessive weight gain, which can increase the risk of complications like gestational diabetes. Focus on eating nutrient-dense foods rather than indulging in extra portions.

2. Heartburn Means Your Baby Will Have a Lot of Hair

A popular myth suggests that if you’re experiencing heartburn during pregnancy, your baby will be born with a full head of hair. While it’s true that heartburn is common during pregnancy, particularly in the second and third trimesters, there’s no scientific evidence linking it to the amount of hair your baby will have. Heartburn typically occurs due to hormonal changes and pressure on your stomach, not your baby’s hair growth.

3. You Should Avoid Exercise While Pregnant

Many people believe that pregnant women should avoid exercise altogether, but this is far from the truth. Unless advised otherwise by your doctor, physical activity during pregnancy is generally safe and beneficial. Regular exercise can help improve circulation, reduce back pain, ease stress, and promote better sleep. Activities like walking, swimming, and prenatal yoga are excellent choices for staying active and healthy.

4. If You Have Morning Sickness, You’re Having a Girl

A common myth suggests that morning sickness is an indicator of the baby’s gender, with some believing that more severe morning sickness means you’re having a girl. While it’s true that some women experience more intense nausea with certain pregnancies, the severity of morning sickness has nothing to do with the gender of your baby. Hormonal fluctuations and individual health factors are the real culprits.

5. You Can’t Dye Your Hair During Pregnancy

Many women worry that dyeing their hair during pregnancy can harm their baby, but there’s no strong evidence supporting this myth. Most hair dyes contain low levels of chemicals, and the amount absorbed through the skin is minimal. However, it’s still a good idea to avoid harsh chemicals and opt for ammonia-free hair dyes, especially during the first trimester, when the baby’s organs are still developing.

6. Pregnancy Is a Nine-Month Journey

While the standard pregnancy duration is often referred to as nine months, it’s technically about 40 weeks (or roughly 10 months) from the first day of your last menstrual period to your due date. This difference in terminology can cause confusion, as many people expect a baby to arrive exactly on their due date, but in reality, only about 5% of babies are born on that specific day.

7. You Must Give Up Caffeine Completely

Many people believe that caffeine is off-limits during pregnancy, but moderate consumption is generally considered safe for most women. Studies suggest that consuming up to 200 milligrams of caffeine per day (about one 12-ounce cup of coffee) doesn’t pose a significant risk to the baby. However, it’s essential to be mindful of other sources of caffeine, like tea, soda, and chocolate, to stay within the recommended limit.

8. You Shouldn’t Travel While Pregnant

It’s often believed that pregnant women should avoid traveling altogether, but most women can travel safely during a healthy pregnancy. In fact, many doctors encourage travel during the second trimester, when morning sickness has typically passed and before the third trimester discomfort sets in. Be sure to check with your healthcare provider before making travel plans, especially if you’re going overseas or have a high-risk pregnancy.

9. You Can’t Sleep on Your Back During Pregnancy

Although it’s true that sleeping on your back during the later stages of pregnancy can cause discomfort or limit blood flow to the baby, it’s not necessary to avoid back sleeping completely. As the pregnancy progresses, most women naturally find it more comfortable to sleep on their sides. Sleeping on your left side is often recommended, as it improves circulation, but occasional back sleeping in the early stages of pregnancy isn’t harmful.

10. You Need to Buy a Lot of Expensive Baby Gear

There’s a common myth that you need to invest in an entire nursery full of expensive baby gear before your baby arrives. While some essentials, like a crib, car seat, and diapers, are necessary, many of the more expensive items (like fancy strollers or clothing) are not required for your baby’s health or safety. It’s best to focus on the basics and only buy what you truly need, especially since babies grow quickly, and you might not get as much use out of some items as you think.

Conclusion

Pregnancy is filled with a lot of advice, and not all of it is accurate or helpful. By debunking these common myths, you can avoid unnecessary stress and confusion during your pregnancy. Remember to always consult your doctor when in doubt about anything related to your health or your baby’s well-being. Stay informed, trust your body, and enjoy the wonderful journey of pregnancy!
