Only humans, monkeys, apes and free-tailed and leaf-nosed bats, and elephant shrews menstruate. In most animals, the uterus lining is reabsorbed into the body if a female does not become pregnant after releasing an egg from the ovary.Women get menstruation every month, but we also don't know everything that we should know about our periods or what happens when we get it.
