What it is
A migraine pregnant, a headache second trimester, a dull band of pressure most days: headaches are one of the most common complaints in pregnancy. Hormone shifts, less caffeine, poor sleep, low blood sugar, and thirst all play a part. About 4 in 10 pregnant women get headaches, most in the first trimester.
What's typical
Tension headaches feel like pressure on both sides and ease with rest, food, and water. Migraines are one-sided and throbbing. Many mothers with migraine see them fade from week 12 on. A new, severe headache after week 20 is a different matter.
What's known
ACOG says most headaches in pregnancy are not dangerous and lists rest, water, food, and a common over-the-counter pain reliever as the usual start; ask your provider. A severe headache after 20 weeks with vision changes, swelling, or pain under the ribs is treated as preeclampsia until a blood pressure check says otherwise.
What helps
- Eat something with protein and drink a big glass of water. Low blood sugar and thirst are the most common causes.
- Lie down in a dark, quiet room for 20 minutes.
- Keep caffeine steady if you drink it. Dropping it suddenly brings headaches on.
