So, maybe you’re an expecting mom! I know how it can feel worrying when you notice a fever. While many mild fevers are caused by common infections, it’s important to know when it’s harmless and when you should call your doctor right away. When you understand the signs, causes, and safe treatments, you can protect both yourself and your baby… and then hopefully, not worry!

What Counts as a Fever in Pregnancy?

A temperature above 100.4°F (38°C) is generally considered a fever in pregnancy. Even a slight rise can leave you feeling tired or achy, so please, know that it’s worth paying attention to your body’s signals.

Common Causes of Fever During Pregnancy

Many moms find that the usual culprits are the same as outside pregnancy, but with some added risks:

• Viral infections: colds, flu, or COVID-19 (which by and large, is just another viral cold).
• Urinary tract infections (UTIs): more common in pregnancy due to hormonal changes.
• Foodborne illness: listeria or salmonella can come from undercooked meat, unpasteurized cheese, or contaminated produce (and why it really is good to focus on primarily plant-based eating, at least to replace those risky items, naturally).
• Other infections: throat, ear, or respiratory infections.

Pro tip: Did you know? Pregnant women are more susceptible to foodborne illness because of changes in the immune system.

When to Call Your Doctor Immediately

Not every fever is dangerous, but some symptoms mean you should reach out right away:

• Fever above 100.4°F (38°C) that doesn’t come down with rest or fluids.
• Fever lasting more than 24-48 hours.
• Fever with chills, rash, severe headache, or shortness of breath.
• Fever with abdominal pain, contractions, or reduced baby movement.
• Any fever in the first trimester, since early fevers can sometimes be linked to complications.

Here are Safe Ways to Lower a Fever in Pregnancy

Most mild fevers improve with simple home care:

• Rest: Give your body time to heal. Take the weight off.
• Fluids: Water, broths, and hydrating foods like watermelon or cucumber.
• Cool compress: A damp cloth on your forehead or back of the neck can bring comfort.
• Acetaminophen (paracetamol): Generally safe in recommended doses, but always check with your doctor first.

Pro tip:⚠️ Avoid ibuprofen or aspirin unless your healthcare provider specifically tells you otherwise.

Foods & Nutrients that Help Support Immunity

Keeping your immune system strong is one of the best ways to prevent illness in the first place. It’s health-101, right? But it’s worth repeating. Incorporate these foods:

• Vitamin C: Citrus fruits, strawberries, kiwi, bell peppers.
• Iron: Lentils, beans, spinach, pumpkin seeds, fortified cereals, lean beef or poultry.
• Zinc: Pumpkin seeds, beans, whole grains, eggs, poultry.
• Omega-3s: Walnuts, chia seeds, flax, salmon, sardines.

Pro tip: Did you know that lentils have more iron per cup than beef. They’re a fantastic plant-powered way to support healthy blood levels.

Final Thoughts for Moms

Most fevers in pregnancy are mild and pass quickly, but always listen to your instincts. If something feels “off,” call your provider. Staying hydrated, eating balanced meals, and resting as much as possible will not only help you recover but also support your growing baby.
