Nosebleeds at 18 Weeks Pregnant

Nosebleeds (epistaxis) are very common in pregnancy, affecting up to 20% of women. The increased blood volume and hormonal effects on nasal mucous membranes make nasal blood vessels more prone to rupture.

👶 What's Happening at Week 18

Your baby is now the size of a bell pepper.

  • If female, the uterus and fallopian tubes are formed.
  • If male, genitals may be visible on ultrasound.
  • Myelin (nerve coating) begins forming.

🔬 Why You're Experiencing Nosebleeds at Week 18

  • Blood volume increases by 40–50%, putting more pressure on nasal blood vessels
  • Estrogen causes the nasal mucous membranes to swell and become more vascular
  • Nasal congestion (pregnancy rhinitis) leads to more nose blowing and irritation
  • Dry air, especially in heated indoor environments
  • Blowing the nose too forcefully

💊 Relief Tips for Week 18

1
Lean Forward, Not BackWhen a nosebleed starts, sit down and lean slightly forward — not backward. Leaning back causes blood to run down the throat.
2
Pinch the Soft Part of the NoseUsing your thumb and finger, pinch the soft part of the nose just below the bridge and hold for 10–15 minutes while breathing through your mouth.
3
Avoid Picking or BlowingFor several hours after a nosebleed, avoid picking or blowing the nose to allow the blood vessel to fully heal.
4
HumidifierAdding moisture to dry indoor air prevents nasal dryness that triggers nosebleeds.
5
Saline Nasal SprayKeeping nasal passages moist with saline spray reduces irritation and cracking.

⚠️ Call Your Doctor If…

  • Nosebleeds associated with a head injury
  • Frequent, heavy nosebleeds that are increasing in severity

Frequently Asked Questions

Is it normal to get nosebleeds every day during pregnancy?

Daily nosebleeds are more common in pregnancy than outside it. They are usually harmless. If they are heavy or increasing in frequency, report them to your provider.

Is swallowing blood from a nosebleed dangerous in pregnancy?

Swallowing small amounts of blood is not dangerous but can cause nausea or stomach upset. Leaning forward during a nosebleed minimizes this.

Can a nosebleed cause iron deficiency during pregnancy?

Frequent, heavy nosebleeds could in theory contribute to iron loss, but typical pregnancy nosebleeds are not heavy enough to cause iron deficiency.

When should I go to the ER for a nosebleed during pregnancy?

If a nosebleed doesn't stop after 30 minutes of proper pinching, or if you are losing large amounts of blood and feeling faint, go to the ER or call your provider.
