Nosebleeds can feel dramatic in pregnancy: you bend down, sneeze in a crowded bus, or wake up and notice blood on the tissue. Many parents immediately think, “Is my BP high? Will this harm the baby?” The reassuring part: nosebleeds during pregnancy are common, and most are small front-of-the-nose bleeds that stop with simple pressure. Still, heavier or repeated episodes deserve attention.
Nosebleeds during pregnancy: what’s happening in your nose
What counts as a nosebleed in pregnancy
A nosebleed in pregnancy (medical term: epistaxis) is any bleeding from inside the nose—from a light smear after blowing your nose to a short drip when you bend forward. Many nosebleeds during pregnancy start in the front part of the nasal septum, where tiny blood vessels sit close to the surface. This typical anterior location explains why bleeding often comes from one nostril and why pressure works.
What it can look like (spotting, clots, one nostril or both)
You might see a few spots, a brighter flow, or small clots (blood sitting briefly or mixing with mucus). Bleeding is often one-sided, it may look like both nostrils if the lining is irritated or blood crosses the septum.
Swallowing a little blood can cause metallic taste and nausea, sometimes vomiting later. Unpleasant, but not automatically dangerous.
Why it can feel more frequent than usual
Pregnancy can make the nasal lining congested and fragile at the same time. With higher blood flow through delicate vessels, even minor irritation—dry AC air, sneezing, rubbing, or gentle blowing—can trigger nosebleeds during pregnancy.
How common are nosebleeds during pregnancy?
How often they happen and when they show up
They are common: around 1 in 5 pregnant women experience nosebleeds during pregnancy. They can occur in any trimester, but many parents notice them more in the second and third trimesters.
Seasonal, indoor air, and nighttime patterns
In India, patterns often match the environment:
- AC use and dry indoor air
- winter dryness in some regions
- dust and pollution
Night-time nosebleeds are common too: lying down can worsen congestion, and dry bedroom air can crack the lining.
Why nosebleeds happen during pregnancy
Hormones and increased blood flow making vessels more fragile
Estrogen and progesterone increase blood flow to mucous membranes and promote vasodilation. Pregnancy also increases blood volume by about 40–50%. The result is a nasal lining that is more swollen and easier to bleed—one reason nosebleeds during pregnancy can feel frequent.
Swollen, sensitive nasal lining (pregnancy rhinitis and congestion)
Many women develop pregnancy rhinitis: a blocked nose not caused by infection. Swelling stretches the lining, making surface vessels more likely to break, especially with frequent wiping or blowing.
Dry air, dehydration, and irritated mucosa
Dry mucosa can crust and crack, exposing tiny vessels. AC, heating, cold air, and low fluid intake add to dryness.
Everyday pressure triggers
Sneezing, coughing, vomiting, forceful nose blowing, and straining with constipation can increase pressure in small nasal vessels and start bleeding.
Triggers and risk factors that can make them more likely
Environmental and lifestyle triggers
Dry indoor air is a big trigger. Tobacco smoke (including secondhand smoke), dust, pollution, and strong cleaning fumes can inflame the lining. Nose rubbing/picking and forceful blowing also increase risk.
Infections and allergies
Colds, sinus infections, and allergies cause swelling, itching, and repeated blowing. Pregnancy rhinitis plus an allergy flare often explains repeated small nosebleeds during pregnancy.
Medical factors to keep in mind
Sometimes epistaxis is not only local irritation. Speak with your clinician if bleeding is unusual, very frequent, heavy, or paired with other symptoms:
- High blood pressure in pregnancy, including preeclampsia warning patterns
- Gestational thrombocytopenia (low platelets) or another hemostasis issue
- Medicines that affect bleeding, including prescribed low-dose aspirin or anticoagulants (do not stop prescribed medication on your own)
Rarely, a benign nasal growth (pyogenic granuloma) can bleed easily, especially if bleeding is always from the same spot or there is nasal blockage.
Nosebleeds during pregnancy by trimester (and after birth)
First trimester
Mild nosebleeds during pregnancy can happen early due to hormonal shifts and dryness, and usually stop quickly with pressure.
Second trimester
As blood volume and congestion increase, episodes may become more noticeable, especially during colds or allergy season.
Third trimester
Late pregnancy can bring more frequent episodes. Be extra attentive if bleeding is heavier, lasts longer, or comes with severe headache or vision changes.
After delivery
Hormones drop after birth and blood volume shifts back toward baseline. Nosebleeds usually reduce over days to weeks. Persistent or increasing bleeding postpartum deserves medical advice.
What’s normal and what may deserve attention
Light, occasional bleeding that stops quickly
A brief episode that stops with correct pressure within 10–15 minutes and does not leave you dizzy usually fits common pregnancy changes.
Frequent nosebleeds
Recurrent episodes over several days deserve discussion. Often it is dryness or rhinitis, but it can also relate to medication effects, a local lesion, low iron, or less commonly platelet/clotting issues.
Heavy bleeding, long-lasting bleeding, or repeated restart
Bleeding lasting beyond 20–30 minutes despite proper technique, feeling heavy, or restarting soon after stopping should be assessed.
When symptoms around the bleed matter
If nosebleeds during pregnancy come with lightheadedness, weakness, fainting, unusual paleness, breathlessness with mild effort, racing heart, or extreme fatigue, seek prompt medical advice. These symptoms can reflect significant blood loss, iron deficiency anaemia, or another medical issue.
How to stop a nosebleed safely while pregnant
Sit up and lean forward
Sit upright and lean forward slightly. This reduces pressure and prevents blood from running down the throat.
Where to pinch and how long to hold pressure
Pinch the soft part of the nose (below the bony bridge) using thumb and index finger. Hold firm, uninterrupted pressure for 10–15 minutes. Do not release early, the clot needs time.
Cold compress
A cold compress over the bridge can help, but pressure is still the key step.
What to avoid during and right after
Avoid tilting the head back or lying flat. Do not blow your nose immediately after bleeding stops.
Once bleeding stops:
- Avoid forceful blowing and nose picking
- Avoid heavy lifting or intense exercise for about 24 hours
- Prefer gentle saline rinsing if you need to clear mucus
Pregnancy-safe home care and prevention
Moisture routines that help
Moisture is the most reliable prevention. Use saline spray or saline rinses regularly. If the nose is crusty, saline gel or a very thin layer of petrolatum inside the nostrils can reduce cracking. A cool-mist humidifier (especially in the bedroom) often reduces repeat nosebleeds during pregnancy.
Gentle nose habits
Blow gently, one nostril at a time. If you sneeze, try to keep your mouth open to reduce nasal pressure.
Indoor air and irritants
Ventilate when possible, avoid overheating the bedroom, reduce smoke exposure, and avoid strong fumes.
Pregnancy-safe medications and products
Saline is usually safe. For medicated nasal sprays (decongestant, steroid spray, antihistamine), seek medical advice rather than self-starting, especially if you need them repeatedly.
If allergies are driving congestion, your provider may discuss pregnancy-compatible options such as cetirizine or loratadine, or an intranasal corticosteroid like budesonide, fluticasone, or mometasone.
For fever/pain, paracetamol is typically preferred. NSAIDs like ibuprofen are generally avoided after 20 weeks unless specifically advised.
When to call your doctor or midwife
Call if:
- bleeding continues after 20 minutes of correct pressure (or up to 30 minutes despite proper technique)
- episodes are recurrent or heavier
- you take anticoagulants/antiplatelets (including prescribed low-dose aspirin)
- you feel unusually tired, dizzy, short of breath with mild effort, or notice paleness
Warning signs: when to seek emergency care
Seek urgent/emergency care for:
- heavy bleeding that will not stop
- chest pain, breathing trouble, fainting, confusion, very pale/clammy skin
- bleeding from other sites (gums, urine, stools)
- facial/head trauma
- a nosebleed with severe headache, vision changes, upper abdominal pain, marked swelling, or very high BP readings
What a clinician may check and how persistent bleeds are treated
A clinician may examine the nose, check vitals and blood pressure, and review medicines.
If bleeding is frequent or heavy, tests may include:
- CBC (haemoglobin/haematocrit)
- platelet count
- PT/INR and aPTT
- ferritin/iron studies when anaemia is suspected
Treatment may include local moisturising care, topical vasoconstrictor plus silver nitrate cautery for a visible anterior source, or nasal packing. ENT review is more likely if bleeding is recurrent, difficult to control, suspected posterior, or linked with blockage.
Key takeaways
- Nosebleeds during pregnancy are common (often around 1 in 5) due to hormonal vasodilation, increased blood volume, and fragile nasal lining.
- Triggers include dry air, pregnancy rhinitis, colds, allergies, smoke/irritants, vomiting, coughing, and straining.
- First aid: sit upright, lean forward, pinch the soft part for 10–15 minutes.
- Prevention: saline spray/gel, humidifier, hydration, gentle blowing, avoid smoke and strong fumes.
- Get medical advice if bleeding lasts 20–30 minutes, becomes frequent/heavier, or you feel dizzy, weak, unusually tired, pale, or breathless.
