Verified step by step guidance

Understand the primary function of oral contraceptives: they are designed to prevent ovulation, which is the release of an egg from the ovary.

Recognize that oral contraceptives contain hormones, typically estrogen and progestin, which work to inhibit the body's natural cyclical hormones to prevent ovulation.

Learn that oral contraceptives also thicken cervical mucus to prevent sperm from reaching an egg and alter the lining of the uterus to prevent implantation.

Note that oral contraceptives are not immediately effective after the first dose; they usually require consistent use over a period of time to be effective.

Clarify that oral contraceptives do not increase the risk of pregnancy when taken consistently; rather, they significantly reduce the risk of pregnancy when used correctly.
