Dear Reader; The timing of periods depends on the body clock in the brain. The brain sends signals which cause hormonal changes and the hormones are the signal which starts a period. The hormones in BC pills can cause a period to come early or late. An emotional event or physical trauma can cause hormonal changes and thus a period change. Dwight
