Common Pregnancy Myths Explained | Aeroflow Breastpumps

Key Takeaways:

• Most pregnancy myths aren't based on scientific evidence but persist through generations

• Many foods and activities once considered "off-limits" are actually safe in moderation

• Gender prediction methods are fun but inaccurate. Only medical tests can determine your baby's sex

• Always consult your healthcare provider when you're unsure about what's safe during pregnancy

If you're pregnant, you've probably heard your fair share of advice—some helpful, some confusing, and some that makes you wonder what's true and what's a myth. From well-meaning relatives telling you what you can't eat to friends sharing "reliable" ways to predict your baby's gender, pregnancy myths seem to be everywhere.

While many of these beliefs have been passed down through generations with good intentions, separating fact from fiction can help you feel more confident about your choices during pregnancy. Let's walk through some of the most common pregnancy myths and what the science actually says.

Pregnancy myths have been around for centuries, likely because they were the best explanations available to moms before modern medicine gave us better answers. Some myths persist because they're fun (like gender prediction games), others because they contain a tiny kernel of truth that gets exaggerated, some because they carry cultural meanings, and some simply because people want to feel like they have control over pregnancy outcomes.

While these myths can be entertaining, they shouldn't replace medical advice from your healthcare provider.

Myth: You Can't Eat Any Fish While Pregnant

You can—and should—eat fish! It's an excellent source of protein and omega-3 fatty acids that support your baby's brain development. The concern around eating fish comes from high levels of mercury found in certain types of seafood. Steer clear of king mackerel, shark bigeye tuna, orange roughy, and swordfish. Enjoy low-mercury options like salmon, shrimp, and canned light tuna (note: avoid canned chunk white tuna or albacore tuna, as these may have higher levels of mercury than canned light tuna). You should also avoid eating raw fish or sushi.  The FDA recommends eating 8–12 ounces of fish per week.

Myth: You Have to Avoid All Soft Cheeses

Most soft cheeses sold in the U.S. are made with pasteurized milk and are safe to eat while pregnant. Check the label, and if it says "pasteurized," you're good to go! Avoid unpasteurized soft cheeses like imported brie, blue cheese, camembert, and queso fresco.

Myth: Pregnant Women Can't Drink Any Coffee

Good news, mama—you don't have to give up your morning coffee! Most healthcare providers agree that moderate caffeine intake (less than 200mg per day, or one 12-ounce cup) is safe during pregnancy.

Myth: You Should Never Take a Warm Bath

Feeling like taking a comfortable warm bath? Go right ahead! Just keep the temperature below 99°F. For this reason, you should avoid hot tubs, saunas, and steam rooms, which are too hot and can quickly raise your core body temperature. It’s also best to avoid bath bombs, essential oils, and other scented or fragranced products. These may contain ingredients that are not considered safe for pregnancy.

Myth: Hair Dye Is Dangerous During Pregnancy

Many pregnant women continue their regular hair coloring routines without issues. However, you should wait until the second trimester to dye your hair, and always check with your provider first.

Myth: You Shouldn't Be Around Cats

Fortunately, you don't need to rehome your cat! The concern is about toxoplasmosis from cat feces. Have someone else change the litter box, or wear gloves and wash your hands thoroughly if you must do it yourself. Your cat can stay!

Myth: Pregnant Women Shouldn't Exercise

For most women with uncomplicated pregnancies, exercise is beneficial! Most exercises are fine to continue, though you may need modifications as your pregnancy progresses. Always check with your healthcare provider and listen to your body.

Myth: You're Eating for Two, So Double Your Food

You do need extra calories to support your pregnancy, but not double! Most women don't need extra calories in the first trimester. In the second trimester, add about 300-350 extra calories, and in the third trimester, about 450-500. This usually amounts to an extra snack or a sandwich. Instead, focus on eating nutrient-dense whole grains, proteins, and produce rather than just increasing your portions.

Myth: You Can Prevent Stretch Marks with Creams

Stretch marks are largely determined by genetics and hormonal changes. While moisturizing helps your skin feel comfortable, creams, lotions, and oils may not prevent stretch marks. In fact, 50-90% of pregnant women develop stretch marks. It’s a normal part of the experience. 

Myth: Spicy Foods Will Harm Your Baby or Induce Labor

Spicy foods are safe for your baby throughout pregnancy. They might give you heartburn (thanks, pregnancy hormones), but there's no scientific evidence they induce labor.

People have tried predicting their baby's sex for centuries with creative tests and signs, but the most accurate results come from a visit to your healthcare provider. Still, you're probably familiar with a few of these gender prediction myths:

• Carrying high vs. low: Your bump's position relates to your height, body shape, and muscle tone, not baby's gender

• Heart rate: Baby's heart rate varies based on gestational age and activity, not their sex

• Morning sickness severity: Affects moms differently regardless of whether they're having a boy or girl

• Food cravings: Related to hormonal changes and nutritional needs, not gender

• Ring test: Swinging a ring from a thread in front of your belly is no more accurate than flipping a coin

How to really determine your baby's sex: Noninvasive prenatal testing (NIPT) blood work can detect a baby's sex as early as 10 weeks, or an anatomy ultrasound around 20 weeks.

As your due date approaches, you might hear about various "natural" methods to start labor. Most are just myths:

• Walking: Can help baby settle into your pelvis but won't necessarily start labor

• Eating spicy foods, pineapple, dates: Delicious, but no solid evidence they induce labor

• Having sex: Minimal effect and won't start labor unless your body is ready

• Taking castor oil: Can cause digestive upset and dehydration

• Nipple stimulation: Some studies suggest that medically supervised nipple stimulation may help start labor, but it is not a guaranteed method and should be done cautiously under guidance from your healthcare provider.

Those final days before meeting your little one might feel like a lifetime, but remember: taking this time to rest, nourish yourself, and mentally prepare can help you feel stronger and more ready for labor when your baby and body are ready. If induction becomes medically necessary, your healthcare provider will guide you to the safest and most effective method, often using medications such as oxytocin or prostaglandins under careful supervision.

Answering More of Your Burning Questions

In addition to fielding myths, it's natural to have other questions about pregnancy as a mom-to-be. Here are some FAQs:

What Is the Oldest Age to Get Pregnant Naturally?

While fertility declines with age, women can get pregnant naturally into their 40s and even early 50s. The oldest recorded natural pregnancy was 59-year-old Dawn Brooke in 1997. Because most women experience menopause between ages 45-55, pregnancies after 45 are very rare. 

What Is the Hardest Month of Pregnancy?

This varies for each mom. Many find the first trimester to be the most challenging period due to morning sickness and fatigue. Others struggle most with the third trimester when physical discomfort peaks. The "hardest" month and trimester are different for everyone, and your feelings are valid wherever you are!

While pregnancy myths can be a fun way to connect with other moms and share anecdotes, they shouldn't guide your health decisions. When in doubt, trust your healthcare provider over well-meaning advice. They can give you personalized guidance based on your specific situation.

And remember: every pregnancy is unique. What's normal for one mom might be different for another. Focus on taking care of yourself, staying informed through reliable sources, and trusting your body as it goes through the journey of growing your baby.
