If you’re pregnant and feeling stuffy, scratchy-throated, or just plain run-down, you’re not imagining it — colds are common during pregnancy, and most are mild and short-lived. The bigger question for most expecting parents isn’t whether they’ll catch a cold (most do, more than once), but what’s actually safe to take for it, what to avoid, and how to tell a garden-variety cold apart from something that needs medical attention.
This guide walks through how to tell a cold from pregnancy congestion (or the flu, or COVID), what treatments are generally considered safe, what to steer clear of, and the specific warning signs that mean it’s time to call your provider.

Always check with your OB-GYN, midwife, or pharmacist before starting any medication during pregnancy — recommendations can vary by trimester, country, and individual health history.
Is It Really a Cold? (Cold vs. Pregnancy Rhinitis vs. Flu vs. COVID)
Pregnancy hormones increase blood flow to the mucous membranes in your nose, which can cause swelling and congestion on their own — a condition sometimes called pregnancy rhinitis. It can feel a lot like the start of a cold, minus the sneezing, sore throat, or cough that usually come with an actual viral infection.
Here’s a quick way to tell them apart:
| Symptom | Common Cold | Pregnancy Rhinitis | Flu | COVID-19 |
|---|---|---|---|---|
| Runny/stuffy nose | Yes | Yes | Sometimes | Sometimes |
| Sneezing | Yes | Occasionally | Occasionally | Occasionally |
| Sore throat | Yes | No | Yes | Sometimes |
| Cough | Yes (mild) | No | Yes | Yes, can be persistent |
| Fever | Rare/low-grade | No | Common, often high | Common |
| Body aches | Mild or none | No | Often severe | Often present |
| Onset | Gradual | No clear onset; comes and goes through pregnancy | Sudden | Variable |
If your only symptom is nasal congestion with no sore throat, cough, or fever, pregnancy rhinitis is a likely culprit. If you have a sore throat, sneezing, and a mild cough but feel otherwise okay, that points toward a common cold. A sudden onset with fever and body aches leans toward flu, and any combination of fever, cough, and loss of taste/smell warrants a COVID test. If you’re unsure or symptoms feel more intense than a typical cold, it’s worth calling your doctor or health facility before going in for an in-person visit — they may want to test you for flu or COVID rather than assume it’s a cold.
Will a Cold Hurt My Baby?
This is usually the first and most pressing question, and the reassuring answer is: a typical common cold is unlikely to harm your baby. The virus itself is generally handled by your immune system the same way it would be if you weren’t pregnant, and colds don’t cross the placenta the way some other infections can.
What matters more than the cold itself is how it’s managed. A few specific things are worth paying attention to:
- Fever. A high fever, rather than the cold virus itself, is the thing to watch most carefully — sustained high body temperature in early pregnancy has been associated with developmental risks in some research, so fever should be brought down and reported to your provider rather than left untreated.
- Severity and duration. Illnesses that turn into something more serious, like bronchitis or pneumonia, carry more risk than a mild cold that resolves in under two weeks.
- It’s not the flu. Flu is a different illness from a cold, and pregnant women — particularly in the second and third trimester — are at higher risk of flu complications such as pneumonia, and in rare cases, more serious outcomes. This is part of why a flu shot during pregnancy is routinely recommended.
In short: the sniffles themselves aren’t the danger. Fever, severity, and ruling out flu or COVID are the things worth your attention.
Safe Ways to Treat Cold Symptoms While Pregnant
Medications: What’s Generally Considered Safe (and Where Guidance Differs)
This is the area where competitor advice tends to get muddiest, mostly because guidance differs by country and by trimester — something worth knowing upfront so you’re not confused by conflicting advice online.
- Acetaminophen (Tylenol/paracetamol): Widely considered an acceptable option for fever and pain during pregnancy when used as directed and not exceeded. It’s the pain/fever reliever most consistently approved across US and UK guidance, though some research has prompted ongoing discussion about minimizing use to what’s necessary. Discuss frequency and dosage with your provider rather than self-managing for an extended period.
- Ibuprofen and other NSAIDs: Generally advised against for treating a common cold during pregnancy, and especially avoided in the third trimester, where NSAID use is more strongly discouraged. Use only if specifically directed by your provider.
- Decongestants (pseudoephedrine, oxymetazoline sprays): This is where guidance genuinely diverges. UK and NHS-aligned sources recommend avoiding oral and nasal decongestants throughout pregnancy. Several US health systems describe pseudoephedrine as an acceptable option in the second and third trimester, but generally advise avoiding it in the first trimester. Given this split, decongestants are a clear “ask your pharmacist or provider first” category rather than a default yes or no.
- Cough suppressants (dextromethorphan) and expectorants (guaifenesin/Mucinex): Often described as reasonable options, particularly past the first trimester, when used at the lowest effective dose for the shortest time needed.
- Antihistamines: No antihistamine has uniform “safe in pregnancy” status, though some older-generation options have a longer track record without associated harm. This is a category to run by your provider rather than choose off the shelf.
The practical takeaway: check the active ingredients on any multi-symptom cold product label, avoid combination products that bundle in ibuprofen or a decongestant by default, and confirm anything beyond plain acetaminophen with your OB-GYN, midwife, or pharmacist — especially in the first trimester, when caution is highest.
Drug-Free and Natural Remedies
These options carry no medication-related uncertainty and are worth trying first or alongside anything your provider approves:
- Rest. Your body needs more recovery time during pregnancy; resist the urge to push through.
- Fluids. Water, herbal teas, and broths help with hydration and can ease a sore throat.
- Saline nasal spray or rinse. Clears congestion without any medication involved.
- Honey and warm lemon water. A gentle way to soothe a sore throat (avoid giving raw honey to infants, but it’s fine for the pregnant person).
- Steam or a humidifier. Loosens congestion and can make breathing more comfortable, especially overnight.
- Warm compresses. Applied to the sinuses or forehead can ease pressure-related discomfort.
- Elevating your head while resting. Can reduce nighttime stuffiness.
Preventing Colds During Pregnancy
- Get a flu shot. It’s recommended during pregnancy and reduces your risk of flu-related complications — it cannot give you the flu.
- Wash your hands often, especially after contact with shared surfaces like door handles or shopping carts.
- Limit close contact with anyone who’s sick, where possible.
- Eat well and stay active. A varied diet and pregnancy-safe movement (like walking or swimming) support immune function.
- Ask your provider about prenatal vitamins or supplements like vitamin C or zinc — and be cautious with any new supplement, since not all are appropriate during pregnancy (excess vitamin A, for instance, is specifically discouraged).
When to Call Your Doctor
Most colds during pregnancy resolve on their own within one to two weeks with rest and supportive care. Contact your provider if you notice any of the following:
- A fever, particularly anything reaching or exceeding 100.4°F (38°C)
- Symptoms lasting longer than two weeks without improvement
- Coughing up yellow or green mucus
- Chest pain, shortness of breath, or wheezing
- Severe sore throat, sinus pain, or symptoms that feel disproportionately intense
- Any symptoms that could indicate flu or COVID rather than a cold (sudden onset, body aches, high fever, loss of taste/smell)
When in doubt, it’s always reasonable to call — your provider would rather hear from you for something that turns out to be minor than have you wait through something that wasn’t.
FAQ For Pregnant And Cold Symptoms
Can a cold hurt my baby during pregnancy?
A typical common cold is unlikely to harm your baby. The bigger concerns are fever, which should be managed, and ruling out more serious illnesses like flu or COVID.
What cold medicine is safe to take while pregnant?
Acetaminophen is the most consistently accepted option for pain and fever. Decongestants, NSAIDs like ibuprofen, antihistamines, and combination products vary by trimester and by guidance source — confirm with your provider or pharmacist before taking anything beyond plain acetaminophen.
Is a stuffy nose during pregnancy a cold or just pregnancy?
It can be either. Pregnancy rhinitis causes congestion without other cold symptoms and can come and go throughout pregnancy. If you also have a sore throat, sneezing, or cough, it’s more likely an actual cold.
How long do colds last when you’re pregnant?
Colds during pregnancy often last similarly to or slightly longer than colds outside of pregnancy — commonly five to ten days, sometimes up to two weeks.
When should I call my doctor about a cold while pregnant?
Call if you develop a fever (especially 100.4°F or higher), symptoms lasting more than two weeks, colored mucus, chest pain or breathing difficulty, or symptoms that seem more severe than a typical cold.
Can I take Tylenol, Mucinex, or Sudafed while pregnant?
Tylenol (acetaminophen) is generally considered an acceptable choice for fever and pain. Mucinex (guaifenesin) and Sudafed (pseudoephedrine) are viewed differently depending on trimester and guidance source — many US providers consider them acceptable in the second and third trimester but advise caution in the first. Check with your provider before taking either.
Is it a cold, the flu, or COVID?
Colds tend to come on gradually with sneezing, sore throat, and mild cough. Flu has a sudden onset with fever and body aches. COVID symptoms vary widely but often include fever, cough, and sometimes loss of taste or smell. If you’re unsure, contact your provider — they may recommend testing.
The Bottom Line
A cold during pregnancy is uncomfortable, but in most cases it’s not a danger to your baby. The priorities are managing fever, choosing treatments your provider has confirmed are appropriate for your trimester, leaning on drug-free remedies where you can, and knowing the specific signs — high fever, symptoms past two weeks, colored mucus, or breathing trouble — that mean it’s time to call your doctor.
