If you do not want to forego sex during your fertile days, but also don’t want to get pregnant, you must use an additional method of contraception. Since many women use natural family planning (NFP) as a birth control method so they don’t have to take any hormones, the best contraceptives are barrier methods like condoms, a diaphragm or the FemCap. Before you use these additional contraceptives, be sure to get all the information you can about how to use them.
