How Does Birth Control Work?
Traditional birth control options, such as the vaginal ring, contraceptive skin patch, or birth control pills, were made to mimic the natural menstrual cycle in women. For instance, a package of birth control pills includes 28 pills for 4 weeks. However, only pills for the first 3 weeks contain hormones that can actively inhibit your fertility, while those for the last week should be inactive. When taking inactive pills, you may experience withdrawal bleeding, which is the body’s response to halt the hormones. Keep in mind that it is different from a regular period.
