Have you noticed some other triggers for your migraine attacks or you find the appearance related with your period only?
Do you take some preventive drugs?
Have you experienced this in more than three consequential months?
Migraine that happens only around the period, beginning from 2 days before the start to 2 days after the end, and not at other times of the month, is known as pure menstrual migraine.
Usually, this type of migraine is more severe and more frequent than regular one.
