As long as there is vaginal bleeding, you should not have intercourse. Withdrawal bleeding is usually the bleeding that occurs after taking the emergency contraceptive pill, and sometimes it is more frequent. If you have intercourse at this time, it will easily cause infection in the uterine cavity, endometrial inflammation and pelvic inflammatory disease and blockage of the fallopian tubes, which will have a great impact on future pregnancies. Because the endometrium is also shed at this time of bleeding, so if you have intercourse at this time, bacteria can travel up the infection. Therefore, no matter what time it is, as long as there is vaginal bleeding, you must not have intercourse, this is a minimum of common sense that everyone must master.
