Occurs monthly: Colloquialisms are odd. Since menses occur about every 28 days in human females, there is a periodicity to them. It's an older term meaning regularly occurring. So one gets a period means its that time of the month for the periodic shedding of endometrial tissue absent a fetal implantation.
