How does the pill work?

Contraceptives include short-acting contraceptives, long-acting contraceptives and emergency contraceptives. Short-acting contraceptives and long-acting contraceptives are a mixture of estrogen and progesterone. The main ingredient of emergency contraceptives is a large dose of progesterone. This progesterone can control endometrial hyperplasia, inhibit ovulation, and prevent fertilized eggs from combining and implanting.
