Doctor can examine: A doctor can check to see if there is any worrisome medical issue if a woman had some unusual menstrual cramps. Many women have some variation of their menstrual symptoms on occasion. Some women feel normal after a few days, but others do have bothersome symptoms and follow-up with their doctors. Some symptoms are from changes in hormone levels; some symptoms might not be related to menses.
