Pregnancy Myths Debunked: What’s True and What’s Not?

  Written by Tarryn Adonis
  Published on July 31st, 2025

Pregnancy is a time filled with excitement, anticipation, and, unfortunately, a lot of myths and misconceptions. From old wives’ tales to advice passed down through generations, it can be difficult to separate fact from fiction. While some myths are harmless, others can lead to unnecessary stress or confusion. Here, we debunk some of the most common pregnancy myths to help you navigate this exciting time with more clarity.

1. Myth: You’re Eating for Two

Fact: While it’s true that you need extra nutrients during pregnancy, you don’t need to double your food intake. Instead of eating twice as much, focus on eating nutritious foods that provide the vitamins and minerals you and your baby need. Generally, an extra 300 calories per day during the second and third trimesters is recommended, but this varies from woman to woman. Overeating can lead to unnecessary weight gain and other health issues.

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

Fact: While there’s a popular belief that heartburn during pregnancy predicts a hairy baby, there’s no scientific evidence to support this. Heartburn is more likely caused by hormonal changes that relax the muscles in your digestive system, leading to acid reflux. Although some babies are born with a full head of hair, others aren’t, and heartburn doesn’t play a role in this.

3. Myth: You Shouldn’t Exercise During Pregnancy

Fact: In most cases, regular exercise is beneficial during pregnancy and can help with circulation, reduce stress, and improve overall health. Activities like walking, swimming, and prenatal yoga are generally considered safe. However, it’s important to consult your doctor before starting or continuing an exercise regimen, especially if you have any medical concerns or a high-risk pregnancy.

4. Myth: Carrying High or Low Indicates the Baby’s Gender

Fact: One of the most persistent myths is that carrying a baby high means it’s a girl, and carrying low means it’s a boy. In reality, the way you carry your baby depends on factors like the position of the placenta, your body type, and whether you’re a first-time mom. The only true way to know the gender is through ultrasound, genetic testing, or amniocentesis.

5. Myth: You Can’t Dye Your Hair While Pregnant

Fact: There is no strong evidence that suggests dyeing your hair is harmful during pregnancy. While it’s recommended to avoid harsh chemicals, most hair dyes today are considered safe. If you’re concerned, consider opting for ammonia-free dye or highlights, which don’t touch your scalp. It’s always a good idea to consult your doctor if you have concerns about hair treatments during pregnancy.

6. Myth: You Have to Avoid All Caffeine

Fact: It’s a common belief that caffeine is completely off-limits during pregnancy, but moderate caffeine consumption is generally considered safe. Experts suggest limiting caffeine intake to about 200 milligrams per day (about one 12-ounce cup of coffee). Excessive caffeine intake has been linked to increased risk of miscarriage and low birth weight, so moderation is key.

7. Myth: Pregnancy Glow Means You’re Really Healthy

Fact: The so-called “pregnancy glow” that some women experience—characterized by glowing skin—is often the result of increased blood flow and hormonal changes. However, not all women experience this, and some may even experience skin issues like acne, stretch marks, or pigmentation changes. Your skin’s appearance during pregnancy doesn’t necessarily indicate your overall health; it’s just one of the many effects of pregnancy hormones.

8. Myth: Pregnant Women Should Avoid Sex

Fact: For most women with healthy pregnancies, sex is safe and can continue throughout the pregnancy. However, it’s important to listen to your body and consult your healthcare provider if you have any concerns. There are some situations, such as high-risk pregnancies or complications like placenta previa, where sex might need to be avoided or modified. Always check with your doctor if you have any specific concerns.

9. Myth: You Should Avoid All Fish During Pregnancy

Fact: While it’s true that certain types of fish—especially those high in mercury like swordfish and shark—should be avoided during pregnancy, fish is an excellent source of protein and omega-3 fatty acids, which are beneficial for both mom and baby. Opt for low-mercury options like salmon, trout, and sardines, which can be safely enjoyed a few times a week. Always ensure the fish is cooked properly to avoid foodborne illnesses.

10. Myth: Morning Sickness Means You’ll Have a Girl

Fact: Morning sickness, which affects many women in the early stages of pregnancy, has no correlation with the baby’s gender. The cause of morning sickness is believed to be hormonal changes, specifically increased levels of human chorionic gonadotropin (hCG), and can affect women carrying either a boy or a girl. Some women experience severe morning sickness, while others do not, regardless of gender.

11. Myth: If You Have a Missed Period, You’re Definitely Pregnant

Fact: While a missed period is one of the most common signs of pregnancy, there are several other reasons for missed periods, including stress, hormonal imbalances, weight changes, or certain medical conditions. If your period is late, a pregnancy test is the most reliable way to confirm if you’re pregnant, and it’s always a good idea to follow up with a healthcare provider for further confirmation.

12. Myth: You Should Avoid Hot Baths or Saunas

Fact: While it’s true that excessive heat can be harmful during pregnancy, particularly in the first trimester, moderate heat from a bath or shower is generally considered safe. However, hot tubs, saunas, and steam rooms should be avoided because they can cause your body temperature to rise too much, which can increase the risk of birth defects. If you enjoy hot baths, make sure the water isn’t too hot and avoid soaking for extended periods.
