Nasal Congestion at 36 Weeks Pregnant
Pregnancy rhinitis — nasal congestion caused by pregnancy hormones rather than a cold or allergy — affects up to 30% of pregnant women. It can start as early as the first trimester and persist until delivery.
👶 What's Happening at Week 36
Your baby is now the size of a swiss chard.
- The baby sheds most of the lanugo (fine body hair).
- Fat continues rounding out the cheeks and body.
- The digestive system is ready to process breast milk.
🔬 Why You're Experiencing Nasal Congestion at Week 36
- Estrogen and progesterone cause mucous membrane swelling throughout the body, including nasal passages
- Increased blood volume causes swelling of nasal blood vessels
- Not caused by infection or allergens — purely hormonal
- Pre-existing allergies or colds may worsen alongside pregnancy rhinitis

Frequently Asked Questions
Is it safe to use a decongestant spray during pregnancy?
Oxymetazoline (Afrin) nasal spray is generally considered safe for short-term use (3 days or fewer). Oral decongestants containing pseudoephedrine or phenylephrine are not recommended, especially in the first trimester.
How long does pregnancy rhinitis last?
Pregnancy rhinitis typically lasts throughout pregnancy and resolves within 2 weeks of delivery.
Can nasal congestion during pregnancy cause nosebleeds?
Yes — increased blood volume and sensitive mucous membranes make nosebleeds more common in pregnancy. They are usually harmless.
Can I tell the difference between pregnancy rhinitis and a cold?
Pregnancy rhinitis causes nasal congestion without fever, sore throat, or body aches. A cold typically includes at least one of these additional symptoms.
