Persistent Headache at 34 Weeks Pregnant: When to Call Your Doctor

Experiencing a headache that lasts 9 days at 34 weeks of pregnancy warrants immediate medical evaluation. While headaches are common in pregnancy due to hormonal changes, increased blood volume, and stress, a persistent or severe headache can signal serious conditions such as:

• Preeclampsia: A dangerous rise in blood pressure often accompanied by protein in urine, visual changes, and upper abdominal pain.
• Migraines: Hormonal fluctuations can trigger or worsen migraines.
• Tension headaches: Caused by stress, poor posture, or dehydration.
• Sinus infections: More common due to nasal congestion in pregnancy.

Immediate Steps

1. Contact your healthcare provider today. Describe the headache's duration, intensity, location, and any accompanying symptoms (vision changes, swelling, nausea).
2. Do not take medication without approval. Acetaminophen (Tylenol) is generally considered safe, but NSAIDs (ibuprofen, aspirin) are avoided in late pregnancy.
3. Monitor blood pressure if you have a home cuff.
4. Stay hydrated, rest in a dark room, and apply a cool compress.

Your provider may order blood pressure checks, urine tests, blood work, or an ultrasound to rule out preeclampsia or other complications. Early detection protects both you and your baby.
