Menstrual cramps: A change in your pattern

A change in your pattern of menstrual cramps while you are having your period can be caused by:

• Pelvic infection.
• Hormonal changes or imbalance.
• Growths in or around the uterus, such as endometriosis, cervical polyps, ovarian cysts, or uterine fibroids.

Call your health professional if your menstrual cramps do not respond to home treatment and your discomfort is so severe that you repeatedly miss work, school, or other activities.
