Headache in Early Pregnancy: What to Know

Early pregnancy can alter sleep, appetite, fluid needs, and sensitivity to smells, each of which may contribute to headache. Missing meals, reducing caffeine suddenly, stress, and eye strain can also play a part. Dehydration may bring thirst, darker urine, dizziness, or dry mouth. Nasal blockage from allergic rhinitis, a common cold, or chronic sinusitis can cause facial pressure and headache. COVID-19 may cause headache with fever, sore throat, cough, or body aches. Heat exhaustion can cause headache with heavy sweating, weakness, nausea, and dizziness. Dengue fever may cause headache and fever after exposure in an affected area; fever in pregnancy deserves clinical advice. Headache alone does not confirm a pregnancy complication.

Rest somewhere cool and quiet, drink fluids regularly, and eat small balanced meals if nausea makes eating difficult. Rise slowly if you feel light-headed, and keep a note of the timing, location, severity, triggers, temperature, and accompanying symptoms. Avoid starting, stopping, or combining medicines without checking with a doctor or pharmacist; pregnancy changes which options are suitable. Keep follow-up appointments and mention headaches at your first pregnancy contact, especially if they are new, frequent, or interfering with daily activities.

Seek urgent medical help for a sudden severe headache, fainting, confusion, weakness, numbness, trouble speaking, vision changes, a stiff neck, repeated vomiting, breathing difficulty, or a high fever. Contact your maternity or medical team promptly for a persistent or worsening headache, marked swelling, upper abdominal pain, or a headache with raised blood pressure. Do not wait for a routine appointment if you feel seriously unwell.

Ask which pain-relief options and doses are appropriate for your pregnancy, whether your blood pressure should be checked, and whether another condition could explain the headache. Tell them how far along you are, your medical history, medicines and supplements, fluid intake, fever, visual symptoms, and any recent travel or illness exposure.
