Blood pressure <160/100mmHg (determined at screening visit)
For migraine group: Suffer from migraine/headache +/- 3 days from their period and/or ovulation (mid-cycle) in the previous three menstrual cycles, lasting 4-72 hours with at least two of these characteristics: unilateral location, pulsating or throbbing pain, pain of at least moderate intensity, or aggravated by or causing avoidance of physical activity (walking/ stair climbing). They should be free from headache attacks at other times of the cycle.
