Severe headache at 8 weeks pregnant: what to know

Early pregnancy can bring hormonal changes, disrupted sleep, reduced food intake, and vomiting, all of which may contribute to headache. [Dehydration](/conditions/dehydration/) is more likely when fluids are hard to keep down. A blocked nose or facial pressure may occur with [Allergic Rhinitis](/conditions/allergic-rhinitis/) or [Chronic Sinusitis](/conditions/chronic-sinusitis/). Headache with fever or respiratory symptoms can accompany [Common Cold](/conditions/common-cold/) or [COVID-19](/conditions/covid-19/). These possibilities do not replace an assessment of a severe or unfamiliar symptom.

Rest in a quiet, cool room and sip fluids regularly. Eat small amounts if nausea allows, and note whether the pain follows vomiting, missed meals, heat, or poor sleep. Before taking pain medicine, check with your maternity clinician or pharmacist because some products are unsuitable in pregnancy. Do not stop prescribed treatment without advice. Keep a record of the pain, your temperature if unwell, and any visual or neurological symptoms.

Contact your maternity team or a clinician promptly for a severe headache that is new, persistent, worsening, or not helped by advice-approved measures. Seek emergency help for sudden explosive pain, weakness, confusion, fainting, seizure, vision loss, severe vomiting, a stiff neck with fever, or trouble speaking. Also seek urgent assessment for significant abdominal pain, bleeding, or inability to keep fluids down.

Ask which pain relief is appropriate at eight weeks, whether dehydration or vomiting needs treatment, and whether your blood pressure or examination needs checking. Mention medicines and supplements, recent travel or heat exposure, nasal symptoms, fever, and whether the headache resembles prior attacks such as [Heat Exhaustion](/conditions/heat-exhaustion/) or [Dengue Fever](/conditions/dengue-fever/).
