Menstrual cramps don't cause any other medical complications, but they can interfere with school, work and social activities.

Certain conditions associated with menstrual cramps may have complications, though. For example, endometriosis can cause fertility problems. Pelvic inflammatory disease can scar your fallopian tubes, increasing the risk of a fertilized egg implanting outside of your uterus (ectopic pregnancy).
