How long will emergency contraceptives delay menstruation?
Emergency contraception refers to a contraceptive method used to prevent pregnancy during unprotected sex or a period of time after contraceptive failure, and drug contraception is the most commonly used method. Women who have had unprotected sex due to accidental injury or other reasons, or women who have failed in contraception, such as condom rupture, slippage, and miscalculation of safety period, may consider taking emergency contraceptive measures, which are effective within 72 hours after sexual intercourse. If they have sex again while taking the medicine, the time should be recalculated. After excluding pregnancy, healthy women of childbearing age should apply it within 72- 120 hours after sexual life. The sooner they take it, the better the effect will be, and the failure rate will often be higher if it exceeds 72 hours.
