What causes bleeding after intercourse that stops shortly afterward?

Bleeding during intercourse that stops quickly may be caused by various factors. Some common reasons include: 1. Mucosal injury: Friction or impact during sexual activity may cause minor damage to the vaginal or cervical mucosa, resulting in slight bleeding. Such injuries are usually mild and heal on their own quickly. 2. Hormonal fluctuations: In some cases, changes in hormone levels can lead to instability of the endometrium, causing brief bleeding after sexual intercourse. 3. Medical conditions: Although less common, certain gynecological conditions such as cervicitis or cervical polyps may also cause similar symptoms. If this occurs occasionally and no other discomfort is present, observation may be appropriate for now. However, if the bleeding happens frequently or is accompanied by other symptoms, prompt medical evaluation is recommended.
