Why do some women experience painful cramps every month during menstruation?

A doctor has provided 1 answer

Primary dysmenorrhea: In the absence of a pelvic pathology like fibroids, endometriosis or others, most cases of primary dysmenorrhea are believed to be due to excessive, intense, uncoordinated uterine contractions caused by abnormal prostaglandin production by the endometrium or to inappropriate muscular-vascular responses to prostaglandin-like molecules.
