Why Do Nosebleeds Happen During Pregnancy — and Should You Be Worried?

If you notice a sudden nosebleed during pregnancy, it can be surprising — even alarming — especially if you’ve never had one before. The good news is that nosebleeds are quite common in pregnancy and are usually harmless.

Here’s what’s actually going on, and when it’s worth paying closer attention.

Why Do Pregnant Women Get Nosebleeds?

Pregnancy brings major changes to blood flow and hormones. These changes directly affect the delicate blood vessels inside your nose.

Common reasons include:

• Increased blood volume: Your body produces more blood during pregnancy, putting extra pressure on small blood vessels in the nose.
• Hormonal effects: Higher estrogen levels make nasal blood vessels more sensitive and prone to breaking.
• Dry nasal passages: Pregnancy-related nasal congestion or dry indoor air can irritate the nose lining.
• Frequent nose blowing: Hormonal rhinitis (stuffy nose in pregnancy) can increase irritation.

None of these mean something is wrong with your pregnancy.

When Do Nosebleeds Usually Start in Pregnancy?

Nosebleeds can occur at any time, but they are more commonly reported in the second and third trimesters, when blood volume and hormonal changes are more pronounced.

Some women experience them only once; others may notice repeated episodes.

Are Nosebleeds Dangerous During Pregnancy?

In most cases, no.

Occasional, mild nosebleeds are considered a normal pregnancy symptom and do not harm the baby.

They become a concern only if they are:

• very frequent
• heavy and difficult to stop
• accompanied by dizziness or weakness
• associated with high blood pressure

If any of these occur, it’s best to inform your doctor.

What Can Help Reduce Pregnancy Nosebleeds?

Simple measures often help:

• Keep nasal passages moist using saline spray
• Use a humidifier if the air is dry
• Avoid picking or forceful nose blowing
• Stay well hydrated
• Apply a small amount of petroleum jelly around the nostrils (external use only)

These steps reduce irritation and dryness.

How Should I Stop a Nosebleed Safely?

If a nosebleed happens:

• Sit upright and lean slightly forward
• Gently pinch the soft part of your nose
• Breathe through your mouth
• Hold pressure for 10–15 minutes

Avoid lying down or tilting your head back.

When Should I Call My Doctor?

Contact your doctor if:

• nosebleeds are frequent or severe
• bleeding lasts longer than 20 minutes
• you feel faint or weak
• you have high blood pressure or swelling

These signs may need evaluation.

A Calm Reassurance

Pregnancy makes the body more sensitive — and the nose is no exception.
While nosebleeds can feel dramatic, they are usually just another side effect of your body adjusting to pregnancy.

If something feels off or persistent, checking in with your doctor is always the right call.
