In brief: Prevent ovulation

The ovary wants to release an egg every month, and the production of the cyst to release that egg can start as early as the 3rd or 4th day after your period starts.
Starting low-dose birth-control pills on the first day of your menstrual period ensures the ovulation process is prevented from ever beginning.
