What causes vaginal bleeding during intercourse in women?

Vaginal bleeding during intercourse in women may be caused by various factors: 1. If intercourse occurs just before menstruation, the bleeding might be an early sign of an upcoming period, which is usually not a cause for concern. 2. If a woman has vaginitis, inflammation can cause congestion and swelling of the vaginal lining, making it prone to bleeding during intercourse due to friction and irritation; in such cases, prompt medical treatment for the infection is necessary. 3. If a woman engages in intercourse without knowing she is pregnant, uterine stimulation may lead to threatened miscarriage, presenting as vaginal bleeding; this situation requires immediate medical attention to ensure fetal safety. 4. Vaginal bleeding during intercourse should never be ignored; the underlying cause should be promptly identified and appropriately managed.
