HOW DO PILL AND PATCH CONTRACEPTIVES WORK?
The pill and the patch work in a very similar way. Combined birth control pills and the birth control patch contain two hormones: estrogen and progestin. Estrogen works to develop the lining of your uterus (womb) and progestin adds thickness and depth to that lining. To use a tree image, the estrogen is like the branches and the progestin is like the leaves. A tree is not the same without both. The presence of estrogen and progestin, in the right amounts at just the right time in your cycle, is necessary for the release of an egg from the ovary. Contraceptives medications work to by preventing the release of an egg from your ovaries. Since pregnancy requires the union of a sperm and egg and there is no egg released, you will not get pregnant. Contraceptive medication also helps to stabilize conditions such as heavy periods, extreme cramping, and irregular cycles by providing a consistent and appropriate level of hormones in the body. It is important to use your pills or patch correctly
