Patient's question:
The other day, I had sex with my boyfriend for the third time, and then a few days later, I experienced withdrawal bleeding. It lasted about four days, and the amount of blood was similar to my usual period. After the withdrawal bleeding stopped, how should I estimate my menstrual cycle again? Is it safe within three days of the withdrawal bleeding?Doctor's answer:
For the issue you mentioned, if a woman experiences vaginal withdrawal bleeding due to taking emergency contraception, it can interfere with normal menstruation. Regarding your question itself, the menstrual cycle after taking the medication is irregular, making it impossible to accurately determine the cycle time. Additionally, the three days after withdrawal bleeding do not constitute a safe period. After taking emergency contraception, withdrawal bleeding may occur again. Withdrawal bleeding can be considered as one menstrual period, and the next expected period should be estimated based on the time of withdrawal bleeding.Recommendation: The three days after the withdrawal bleeding has subsided should be considered a safe period, but it is best to take contraceptive measures to ensure safety.
