How long after taking emergency contraception can one have sexual intercourse?

Sexual intercourse can occur at any time after taking emergency contraceptive pills, but subsequent contraceptive measures should be properly implemented. The detailed analysis is as follows:

Emergency contraceptive pills are effective only for unprotected sexual activity that occurred before taking the pill. If no contraceptive measures are taken and sexual intercourse occurs again after taking the pill, there remains a risk of pregnancy. Especially during a woman's ovulation period, even after taking emergency contraceptive pills, there remains a possibility of sperm combining with an egg following subsequent intercourse. Therefore, it is recommended to use reliable contraceptive methods such as condoms during sexual intercourse, avoiding frequent use of emergency contraceptive pills within a short period to reduce their impact on the body's endocrine system.

If symptoms such as nausea and vomiting occur after taking emergency contraceptive pills, and the body is relatively weak, it is not recommended to engage in sexual activity immediately. One should rest and observe first, resuming sexual activity only after the discomfort has subsided. Additionally, emergency contraceptive pills may cause menstrual cycle disorders, making it difficult to accurately determine the ovulation period. To prevent unintended pregnancy, strict contraception should be practiced during every sexual encounter, and emergency contraceptive pills should not be used frequently as a regular contraceptive method.

Effective contraception must be used during sexual intercourse after taking emergency contraceptive pills. At the same time, close attention should be paid to one's menstrual cycle and physical condition. If abnormalities such as a delayed menstrual period of more than one week occur, a pregnancy test should be promptly conducted, and medical consultation sought if necessary.
