Menstrual cramps usually start shortly before the menstrual period, peak within 24 hours after their onset, and subside after a day or two. Menstrual cramps can range from mild to severe. Mild menstrual cramps may be barely noticeable and short-lived, and they are sometimes felt only as a sense of mild pressure in the abdomen and pelvis. Severe menstrual cramps can be so painful that they interfere with a woman's regular activities for several days.
