procedure
The Cleveland Clinic provides a procedure for tracking a menstrual cycle: (1) Mark the first day of bleeding on a calendar with an X, designating it as day one. (2) Continue marking each day of bleeding with an X until bleeding stops. (3) When bleeding starts again, mark that day with an X as day one. (4) Count the number of days between each first X to determine cycle length, and count the number of X's to determine the duration of bleeding.
