Patient's question:
Medical Description: Female patient, 23 years old. Took emergency contraception pills (Mifepristone) before sexual intercourse and is worried about pregnancy. Previous Treatment and Effect: Has never used emergency contraception pills. Desired Help: What should be done if pregnancy is possible afterward?Doctor's answer:
Hello, taking emergency contraception pills within 72 hours of intercourse will be effective in preventing pregnancy. After taking the pills, you should experience withdrawal bleeding in about half a month. If withdrawal bleeding occurs, it indicates that contraception has been successful. Based on the information you provided, the absence of a menstrual period after taking emergency contraception pills is a result of menstrual disruption caused by the pills. Generally, the delay should not exceed one week. If your period does not arrive within one week, please visit a hospital for a check-up. From your specific description, there is a possibility of contraceptive failure with emergency pills, but since you have already taken them, the success rate is still relatively high. If your period has not arrived after the expected cycle, it is recommended to have another check-up.
