This study is designed to make comparisons between acupuncture and acupressure for preventing menstrual migraine (MM). Whether acupuncture is superior to acupressure is the most interesting point of this study. First of all, females will be screened for eligibility. Then, all participants who meet the inclusion criteria will be asked to keep a headache migraine diary for three months as baseline data. The diaries will then be collected before the first treatment. Then, all the participants will receive the corresponding interventions on the eighth, fifth and second days before the estimated first day of menstruation (determined individually from the diaries) in each month for three months (menstrual cycle), making a total of nine treatment sessions. After the whole treatments, there will be a three-month follow-up period. All the participants will be asked to complete the headache diaries every month from baseline to the end of the study. The diaries recording data from the fourth to the ninth month will then be collected at the end of the ninth month for the second time indicating the end of the study for the participants. In case of an acute migraine attack, participants will not be restricted from using "normal" medications.
