Pregnancy Dos and Don'ts: Your Complete Safety Guide

What Are the Dos and Don'ts of Pregnancy?

The moment you announce your pregnancy, the advice starts pouring in. Your mother, your mother-in-law, your coworker, the stranger at the grocery store — everyone has an opinion about what you should or should not be doing. Some of it is helpful, some of it is outdated, and some of it is outright wrong.

This guide cuts through the noise. Based on current guidelines from ACOG, the CDC, the FDA, and other major health organizations, here is a comprehensive, evidence-based list of pregnancy dos and don'ts organized by category.

Before diving into the lists, it helps to understand why some rules feel contradictory. Guidance evolves as research accumulates, and a recommendation that was standard practice a generation ago, such as blanket exercise restriction, has been revised as evidence accumulated. Recommendations also shift with trimester. A position that is harmless at 12 weeks, such as lying on your back during a stretch, becomes worth avoiding at 30 weeks because the growing uterus can compress major blood vessels. When you read conflicting advice, check whether the sources are talking about the same stage of pregnancy and whether they cite current professional guidelines. This page reflects the most widely accepted guidance, but your own provider knows your medical history and can tailor every item on these lists to your situation.

What Foods and Drinks Are Safe During Pregnancy?

DO:

• Eat a balanced, varied diet — Focus on fruits, vegetables, whole grains, lean protein, and healthy fats. A nutrient-rich diet supports your baby's development. See our complete pregnancy nutrition guide for details.
• Take a daily prenatal vitamin — Essential for filling nutritional gaps, especially folic acid, iron, and DHA
• Wash fruits and vegetables thoroughly — Removes potential bacteria and pesticide residue
• Cook meat to safe temperatures — Use a food thermometer; poultry should reach 165°F, ground meats 160°F, and whole cuts of beef/pork/lamb 145°F
• Choose pasteurized dairy — Check labels on cheese, milk, and juice
• Stay hydrated — Aim for 8-10 glasses of water per day
• Eat 2-3 servings of low-mercury fish per week — Salmon, shrimp, canned light tuna, and cod are excellent sources of omega-3s
• Practice good food safety — Wash hands before preparing food, keep raw and cooked foods separate, refrigerate perishables promptly

DON'T:

• Don't drink alcohol — No amount is considered safe during pregnancy. Alcohol crosses the placenta and can cause fetal alcohol spectrum disorders
• Don't eat raw or undercooked meat, poultry, or seafood — Risk of Salmonella, E. coli, and Toxoplasma
• Don't eat raw sushi (with raw fish) — Cooked sushi is fine
• Don't consume unpasteurized dairy — Soft cheeses like brie, camembert, and blue cheese (unless labeled "made with pasteurized milk")
• Don't eat high-mercury fish — Shark, swordfish, king mackerel, tilefish, and bigeye tuna
• Don't exceed 200mg of caffeine per day — About one 12oz cup of coffee. Watch for caffeine in tea, chocolate, energy drinks, and some medications
• Don't consume raw eggs — Avoid homemade Caesar dressing, raw cookie dough, and hollandaise sauce made with raw eggs
• Don't eat deli meats without heating — Heat until steaming to kill potential Listeria
• Don't consume excessive vitamin A — Avoid liver and high-dose vitamin A supplements, which can cause birth defects

Why do the food rules lean so heavily on bacteria and parasites? Listeria deserves special respect because it can grow at refrigerator temperatures, which is why deli meats and soft cheeses carry warnings even when they look and smell perfectly normal. Toxoplasma, the parasite behind the cat litter caution, can also arrive on unwashed produce or undercooked meat, so hand washing and safe cooking temperatures do double duty. Salmonella and E. coli are more familiar, but pregnancy suppresses parts of the immune response, so an infection that would leave another adult mildly uncomfortable can cross the placenta or trigger severe dehydration. None of this means you need to fear your kitchen. It means a food thermometer, a colander, and a quick label check cover most of the real risk.

Which Medications and Supplements Are Safe During Pregnancy?

DO:

• Take your prenatal vitamin daily — As recommended by your healthcare provider
• Check with your doctor before taking any new medication — This includes over-the-counter drugs, herbal supplements, and essential oils
• Keep taking prescribed medications — Some conditions (asthma, thyroid disorders, depression) require ongoing treatment. Do not stop without consulting your doctor — untreated conditions can harm your baby
• Get recommended vaccinations — The flu shot and Tdap (tetanus, diphtheria, pertussis) vaccine are recommended during pregnancy. COVID-19 vaccines are also considered safe and effective

DON'T:

• Don't take ibuprofen (Advil, Motrin) — Especially after 20 weeks, as it can affect your baby's kidney development and reduce amniotic fluid
• Don't use retinoids (topical or oral) — Including Retin-A, Accutane, and many anti-aging skincare products
• Don't take herbal supplements without medical guidance — "Natural" does not mean safe during pregnancy. Many herbs can stimulate uterine contractions or affect fetal development
• Don't self-medicate — Always check with your healthcare provider, even for common complaints like headaches or colds

Generally Considered Safe (With Doctor's OK):

• Acetaminophen (Tylenol) for pain and fever
• Most antacids (Tums, Maalox) for heartburn
• Some antihistamines (Benadryl, Zyrtec) for allergies
• Certain antibiotics (when prescribed by your doctor)
• Ondansetron (Zofran) for severe nausea

Timing matters as much as the medication itself. The first trimester is when the organs form, roughly weeks three through eight after conception, so that window carries the highest sensitivity to anything that interferes with development. Later in pregnancy the questions change: ibuprofen after 20 weeks can affect fetal kidney function and amniotic fluid levels, and some medications given near delivery can affect the baby's breathing or bleeding risk. This is why the same drug can appear acceptable in one trimester and restricted in another, and why the answer to almost every medication question starts with a call to your provider or pharmacist. Keep an updated list of everything you take, including supplements and topical products, and bring it to your prenatal appointments so nothing gets overlooked.

What Exercises Are Safe During Pregnancy?

DO:

• Exercise regularly — Aim for at least 150 minutes of moderate activity per week, unless your doctor says otherwise. See our guide to safe exercises during pregnancy.
• Stay active with walking, swimming, prenatal yoga, and stationary cycling — These are excellent choices for most pregnancies
• Listen to your body — Slow down if you feel tired, dizzy, or short of breath
• Stay hydrated during exercise — Drink water before, during, and after your workout
• Do pelvic floor exercises (Kegels) — Strengthening these muscles helps during delivery and postpartum recovery
• Warm up and cool down — Your ligaments are more relaxed during pregnancy, making warm-ups especially important

A hormone called relaxin deserves a mention here. Relaxin rises during pregnancy and loosens the ligaments and joints so your pelvis can accommodate and deliver your baby. The tradeoff is that every joint in your body, including ankles, knees, and the small joints of the spine, becomes a little less stable, which is why twisting and jarring movements carry more injury risk than they used to. Supportive shoes, stable surfaces, and controlled ranges of motion go a long way. Swimmers get a bonus: the water supports your weight, making it one of the most forgiving ways to keep your heart and muscles working. If an activity was part of your routine before pregnancy, you can usually continue a modified version of it with your provider's approval.

DON'T:

• Don't do contact sports — Soccer, basketball, hockey, martial arts
• Don't participate in activities with fall risk — Horseback riding, downhill skiing, rock climbing, gymnastics
• Don't scuba dive — Risk of decompression sickness for the baby
• Don't exercise in extreme heat — Avoid hot yoga, saunas, and outdoor exercise in hot weather
• Don't lie flat on your back to exercise after the first trimester — This can restrict blood flow
• Don't do high-impact or jumping exercises late in pregnancy — Your joints are looser and more prone to injury
• Don't ignore warning signs — Stop and call your doctor if you experience bleeding, dizziness, chest pain, or painful contractions during exercise

Are Your Everyday Activities Safe During Pregnancy?

DO:

• Sleep on your side (preferably left) — Especially after 20 weeks. Check our pregnancy sleep tips for more details.
• Wear a seatbelt correctly — The lap belt should go under your belly, across your hips; the shoulder belt goes between your breasts
• Take care of your mental health — Pregnancy hormones, anxiety, and life changes can affect your mood. Seek help if you are feeling persistently sad or anxious
• Go to all prenatal appointments — Regular checkups are essential for monitoring your health and your baby's development
• Practice good hygiene — Wash your hands frequently, especially after handling raw meat or petting animals
• Use sunscreen — Your skin may be more sensitive to the sun during pregnancy

DON'T:

• Don't clean the cat litter box — Cat feces can carry Toxoplasma gondii, a parasite that can cause serious harm to your baby. Have someone else handle litter box duty.
• Don't use hot tubs or saunas — Raising your core body temperature above 101°F in the first trimester is associated with increased risk of neural tube defects
• Don't smoke or vape — Smoking during pregnancy increases the risk of premature birth, low birth weight, and developmental problems. This includes marijuana.
• Don't use recreational drugs — All recreational drugs carry risks during pregnancy
• Don't avoid the dentist — Dental care is safe and important during pregnancy. Hormonal changes can make your gums more susceptible to inflammation and infection.
• Don't use harsh chemical cleaning products without ventilation — Opt for natural cleaners or ensure the area is well-ventilated

Household cleaning deserves practical detail because it comes up weekly. Ordinary soap and water, diluted vinegar, and baking soda handle most jobs without concern. If you must use a stronger product, such as an oven cleaner or a mold treatment, open windows, run a fan, wear gloves, and step out of the room while it works, then let the space air out before you return. The concern with harsh chemicals is primarily inhalation and skin contact in poorly ventilated spaces, not a single careful use. Never mix products containing bleach and ammonia, because the combination produces toxic gases whether or not you are pregnant. When in doubt, delegate the strong stuff for nine months and save the deep cleaning for after delivery.

Is It Safe to Work and Travel During Pregnancy?

DO:

• Continue working — Most women can work throughout pregnancy with reasonable accommodations
• Take breaks — Stand up, stretch, and walk around regularly if you sit at a desk
• Travel when comfortable — Air travel is generally safe through 36 weeks for uncomplicated pregnancies. Most airlines allow travel until 36 weeks; check with your carrier.
• Wear compression socks when flying — Reduces the risk of blood clots
• Discuss workplace hazards with your doctor — If you work with chemicals, radiation, or do heavy lifting, you may need accommodations

DON'T:

• Don't fly after 36 weeks — Most airlines will not let you board, and you do not want to go into labor at 35,000 feet
• Don't travel to areas with Zika virus without checking current CDC travel advisories
• Don't lift heavy objects — Ask for help, especially in late pregnancy
• Don't stand for extended periods without breaks, especially in the third trimester

Travel comfort improves with a little planning regardless of the destination. On flights longer than a few hours, an aisle seat makes it easy to walk the cabin every hour or so, which supports circulation and reduces stiffness. Drink water steadily, since cabin air is dry, and loosen restrictive waistbands for the trip. For road trips, plan a stop every 90 minutes or two hours so you can get out and move, keep the lap belt low across your hips, and pack snacks that fit your nausea pattern. Bring a copy of your prenatal records if you are far along, along with the phone number of your provider, so any doctor you meet along the way has the essentials at hand.

Is Your Beauty Routine Safe During Pregnancy?

DO:

• Continue your basic skincare routine — Gentle cleansers, moisturizers, and sunscreen are safe
• Get your hair dyed — Most research suggests hair dye is safe during pregnancy, especially after the first trimester. If you are concerned, opt for highlights (which do not touch the scalp) or semi-permanent color.
• Paint your nails — Use nail polish in a well-ventilated area
• Use mineral makeup — Generally considered safe and gentle

A simple rule sorts most beauty products quickly: items that sit on the surface, such as gentle cleansers, moisturizers, mineral makeup, and standard nail polish used in a ventilated room, are generally considered low concern, while products designed to penetrate or peel the skin deserve a closer look. Read ingredient lists for retinol, tretinoin, adapalene, hydroquinone, and high concentrations of salicylic acid, and set them aside until after delivery. When you want an alternative, products formulated with vitamin C, azelaic acid, or glycolic acid in modest concentrations are commonly suggested during pregnancy, though your dermatologist or provider can confirm what fits your skin. Keeping the swap simple makes it sustainable for nine months.

DON'T:

• Don't use retinoid-containing products — Check your skincare labels for retinol, retin-A, tretinoin, or adapalene
• Don't get chemical peels — The active ingredients can be absorbed through the skin
• Don't use teeth-whitening products — Safety during pregnancy has not been established
• Don't use self-tanning pills — Topical self-tanners are generally considered safe, but oral products are not recommended

What Pregnancy Warnings Can You Safely Ignore?

Pregnancy comes with a lot of fear-based advice. Here are some common concerns that are generally not worth stressing over:

• A single cup of coffee — Under 200mg of caffeine per day is fine
• Sleeping on your back occasionally — Your body will wake you up if blood flow becomes an issue
• Bending over — It will not hurt the baby
• Raising your arms above your head — An old wives' tale; this will not wrap the cord around the baby's neck
• Exercise causing miscarriage — Moderate exercise does not increase miscarriage risk in normal pregnancies
• Having sex — Sex is safe throughout a normal pregnancy. Your baby is protected by the amniotic sac and your cervix.
• Feeling stressed — Everyday stress does not harm your baby. Chronic severe stress is worth discussing with your provider, but normal daily stressors are fine.

Notice how many of these worries share a pattern: they describe ordinary movements, foods, or feelings that generations of pregnant people engaged in without harm. Fear-based advice tends to spread precisely because it assigns blame for outcomes that were never anyone's fault, and it thrives in comment sections and older parenting books. The stress you feel about following every rule perfectly can itself become the thing worth managing. Chronic, severe stress is worth raising with your provider, both for your comfort and because sustained high stress deserves real support, but the everyday variety that comes with appointments, work, and a changing body is a normal part of the experience. Treat relaxation as part of the plan, not as a luxury you earn after everything else is done.

When Should You Call Your Doctor During Pregnancy?

Regardless of any guideline, contact your healthcare provider immediately if you experience:

• Vaginal bleeding or spotting
• Severe abdominal pain
• Severe headache that will not go away
• Vision changes (blurriness, spots, flashes of light)
• Sudden swelling of face, hands, or feet
• Fever over 100.4°F (38°C)
• Decreased fetal movement (after you start feeling the baby move regularly)
• Fluid leaking from the vagina
• Signs of preterm labor (regular contractions before 37 weeks, pelvic pressure, low back pain)

Trust your pattern recognition when something feels different. Fetal movement has its own rhythm by the third trimester, and many providers suggest paying attention at the same time each day so you learn what is normal for your baby rather than comparing against a generic number. Keep your provider's daytime line and the after hours instructions somewhere easy to find, such as saved in your phone, because questions rarely arrive at convenient moments. Calling does not need a good reason attached; nurses who staff these lines expect questions about symptoms that turn out to be nothing, and they would far rather reassure you ten times than miss one case that mattered. When you call, note the symptom, when it started, and what makes it better or worse.

How Do You Take Care of Yourself During Pregnancy?

Pregnancy can feel like a long list of rules, but try not to let it overwhelm you. The vast majority of pregnancies progress normally even when the occasional guideline is not followed perfectly. Focus on the big things: eat well, stay active, attend your prenatal appointments, avoid the clear no-nos, and give yourself grace.
