If you're premenopausal and you experience vaginal bleeding after sex now and then, but not often, it probably isn't something to get too worried about. Vaginal bleeding after sex could indicate cervical cancer, but if you've had normal results on routine Pap tests, it's more likely that the cause is another condition.
If you're postmenopausal, however, vaginal bleeding of any sort is considered abnormal until it's been evaluated and a cause determined.
Vaginal bleeding after sex may result from:
- Cervical cancer
- Cervical dysplasia: Is it cancer?
- Friction during sexual intercourse
- Hormone replacement therapy: Cause of vaginal bleeding?
- Inadequate lubrication or foreplay
- Injury to the uterine lining (endometrium) during intercourse, especially in women taking oral contraceptives
- Normal uterine bleeding, if you're just beginning your period or if it has just ended
- Vaginal atrophy
- Vaginal dryness
Causes shown here are commonly associated with this symptom. Work with your doctor or other health care professional for an accurate diagnosis.
