If the patient did not use contraception during intercourse and the patient has not taken the emergency contraceptive pill for more than 72 hours after intercourse, other emergency contraceptive measures should be chosen according to the specific time after the patient has intercourse. If the patient has had intercourse for more than 72 hours but within 120 hours, the patient can also choose oral contraceptives for emergency contraception, for example, the patient can choose the emergency contraceptive pill with mifepristone as the main ingredient, which usually needs to be taken once, one dose of 10mg, its emergency contraceptive effect is relatively high, and the chance of the patient having an unplanned pregnancy is only about 2%-4%. In addition, patients can also choose to place an intrauterine device for emergency contraception. The intrauterine device can interfere with the fertilization of the egg, so it can achieve the effect of emergency contraception, but also requires patients within 120 hours after intercourse.
