Normal menstruation after taking emergency contraceptive pills is mostly indicative of successful contraception, and it is recommended that pregnancy be excepted by using an early pregnancy test.
Taking emergency contraceptive pills is a remedial method to avoid unintended pregnancy after unprotected sex. Due to the high dose of hormones and side effects of emergency contraceptive pills, and the contraceptive efficiency is significantly lower than that of short-acting contraceptive pills, so it is not recommended to take them routinely.
Emergency contraceptive pills are generally not necessary to deal with side effects such as gastrointestinal reactions, irregular vaginal bleeding and menstrual disorders. However, if menstruation is overdue for more than 1 week, pregnancy needs to be ruled out.
Emergency contraceptive pills are only effective for one unprotected sexual intercourse, so women who do not wish to have children can use short-acting contraceptive pills or condoms under the guidance of a doctor.
