(HealthDay News) -- Cramps are a better-known symptom of a woman's period, but about 20 percent of women are also prone to migraine headaches during menstruation.
The Office on Women's Health suggests seeing a doctor if you have any of these symptoms during menstruation:
- Your headaches change.
- Treatments that once worked no longer help.
- You have side effects from your medicine.
- You take hormonal birth control pills and have migraine with aura (seeing bright flashing lights or spots that aren't real).
- Your headaches become worse when you lie down.
