DictionarymenstrualMonthly bleeding cycle
adjective

menstrual

MEN-stroo-ul/ˈmenstruəl/

Relating to the body's cycle of bleeding from the uterus.

During menstrual bleeding, the uterine lining sheds and leaves the body.

An isolated anatomical cutaway of the uterus shows the lining shedding, with a small amount of blood passing through the cervix into the vaginal canal.
Etymology

The base means “monthly,” and the resulting Latin adjective could refer especially to the monthly courses. That specialized use underlies the English connection with uterine bleeding.
