Patient's question:
NoDoctor's answer:
Emergency contraception refers to a method of contraception used within a certain period after unprotected sex or contraceptive failure to prevent pregnancy, with medication being the most commonly used method. Women who have experienced accidental injury or had unprotected sex due to other reasons, or whose contraception has failed (such as condom breakage, slippage, or incorrect calculation of safe days), may consider taking emergency contraception. It is effective within 72 hours after intercourse, and if sexual activity occurs during the medication period, the time needs to be recalculated.
