Periods

Your menstrual cycle is a process that prepares your body for possible pregnancy. During your menstrual cycle, hormones cause your uterus lining to shed and flow out of your vagina. This is the start of your period.

Everyone’s menstrual cycle is different, and cycles can change at different stages in your life.

Learn more about the menstrual cycle, what to expect during your period, period products, conditions related to your period and when to see your doctor.
