I've been having really bad migraines almost every day and i've came on my period twice in one month and they both last really long what could it be?

Menstrually-related: Migraine. Hormonal changes can affect all women with migraine and most women experience an increased frequency of migraine attacks around the time of menses. They typically occur 3-7 days before day 1 of the menstrual cycle. Associated symptoms of menstrual migraine include depression or irritability, fatigue, bloating and breast tenderness. Rec: see headache or orofacial pain specialist.
