Some girls have such severe cramps that they miss one or two days of school each month. Let's discuss some ways to relieve cramps so girls don't miss out on any activities in school and sports, or with friends and family.
Cramps are uterine contractions that are stimulated by chemicals called prostaglandins.
Prostaglandins are released from the lining of the uterus right before and during menstruation. The uterine muscles contract and the pain is commonly felt in the back, pelvis and legs. Most girls experience menstrual cramps during the first one or two days of their periods. On average, U.S. girls begin to menstruate at about 12.5 years, although periods may begin anywhere between age 9 and 16. Menstrual cramps occur in girls who are ovulating most months.
