Is it a problem if there's bleeding again after having sex following the end of menstruation?

　　"Yima" usually refers to menstruation. Bleeding after intercourse immediately following the end of a menstrual period may be caused by retained blood in the uterine cavity, vaginal injury, gynecological inflammation, or other reasons.

　　1. Retained Blood in the Uterine Cavity

　　Right after menstruation ends, if intercourse occurs while residual blood remains in the uterus, it may lead to bleeding during sex. Generally, this condition does not require specific treatment and can be monitored temporarily.

　　2. Vaginal Injury

　　Shortly after menstruation ends, intercourse may cause vaginal trauma due to sexual stimulation. Vaginal tears often occur during involuntary or particularly rough intercourse, which can also result in post-coital bleeding. Attention should be paid to maintaining proper local hygiene to promote recovery.

　　3. Gynecological Inflammation

　　If a woman already has an existing gynecological inflammation, having intercourse right after menstruation may worsen the inflammation and lead to bleeding after sex.

　　It is recommended that patients promptly visit a hospital for abdominal ultrasound, colposcopy, and routine vaginal discharge tests to accurately diagnose the specific nature of any gynecological inflammation, and follow targeted treatments as advised by a physician.
