The emergency contraceptive pill should not be used frequently and should not be taken as a last resort. The instructions for the pill state that it should not be taken more than three times a year. The emergency contraceptive pill contains a large amount of progestin, which affects the formation of fertilized eggs and their implantation, thus achieving the purpose of contraception, and is only suitable for remedial measures after the failure of conventional contraception, and is a kind of first aid. If used for a long time and frequently, it will lead to endocrine disorders in women, thus affecting menstruation, which may appear as menstrual disorders, manifested as early or delayed menstruation, more or less menstrual volume, or in serious cases, amenorrhea, or even infertility consequences. Therefore, it is recommended that women must take good contraceptive measures and reduce the use of emergency contraceptive pills.
