Occasionally, the emergency contraceptive pill may cause withdrawal bleeding, menstrual disorders or irregular vaginal bleeding, and other symptoms. The emergency contraceptive pill was not originally developed to be used for regular contraception, but to make up for the failure of contraception, for example, if a condom is used for contraception and the condom slips or breaks, the emergency contraceptive pill can be taken orally to remedy the situation and avoid pregnancy. It is not recommended to use the emergency contraceptive pill as a regular contraceptive method, but to use condoms or the intrauterine device, both of which can be very effective.
