Abstract

A home-use fertility monitor was used to time perimenstrual prophylaxis in 27 women with menstrual or menstrually related migraine. Cycle length variability was mostly caused by follicular phase variability; the postovulatory luteal phase was relatively constant. The monitor accurately identified ovulation in >90% of cycles, enabling prediction of menstruation and precise timing of perimenstrual prophylaxis. Ninety-seven percent of women found the monitor useful in predicting menstrual migraine attacks.
