Patient's question:
NoDoctor's answer:
Because emergency contraception pills are actually a type of sex hormone, they primarily disrupt the balance of sex hormones in the body, leading to the failure of the fertilized egg to develop normally and eventually die. Generally, withdrawal bleeding can occur 3-7 days after stopping emergency contraception pills, but it is not yet time for this. Whether or not withdrawal bleeding occurs is not a sign of whether contraception is successful; it is necessary to wait for a normal menstrual period. If a normal menstrual period occurs, it indicates that contraception was successful.
