Oral contraceptive pills work because they are hormones. They make your body have the levels of hormone that it would naturally have before ovulation - that means that your body will not produce an egg - and "fools" the body into not being pregnant. It is not 100% perfect (no contraceptive is), but is as close as you can get.

Birth Control can make your period lighter or even stop it altogether by preventing the build-up of the uterine lining. Some types of birth control also regulate the hormones that control your menstrual cycle, which can lead to lighter and more predictable periods.
