Menstrual cramps are pain in the lower abdomen (pelvis) a few days before, during or after a menstrual period. The pain tends to be most intense about 24 hours after periods start and disappears in 2 to 3 days. The pain is usually cramping or a dull, constant ache, but it can be sharp or throbbing and may come and go. Sometimes it spreads to the lower back or legs.
