In the control acupuncture group, the number, duration, and frequency of the sessions will be the same as for the verum acupuncture group. Sterile needles (0.18 mm in diameter and 15 mm in length, DONGBANG Needle, Korea) will be used on acupoints that have no therapeutic effect on either menstruation or migraines, based on the acupuncture text books and acupuncture research literature. The points chosen will be: LR7 (Xiguan), GB35 (Yangjiao), LI12 (Zhouliao), M-BW-1 (Dingchuan). The depth of needle insertion will be as superficial as 3 mm, and without manual rotation, in order to minimize stimulation of the needle.
