Recently I have been getting severe headaches or migraine when starting my period. Why now all of a sudden? It's debilitating and I hate taking med.

Menstrual migraine. begin two days before the menstrual cycle and lasts through day 3 of the cycle. Compared to other migraine attacks, menstrual migraines are more severe and last longer. See your PCP for consultation, tests and menstrual migraine management.
