It is not normal for a woman to have abnormal vaginal bleeding if it is not during her menstrual period. The bleeding that occurs after intercourse is contact bleeding, for which cervical disease is usually the most common consideration. Severe cervical erosion, cervical polyps, and large submucosal fibroids of the uterus can cause bleeding. Some patients with cervical malignant lesions often have contact bleeding as an early symptom, so it is important to pay attention to this condition. It is recommended to go to the hospital in time to improve cervical cancer screening, including cervical cytology, HPV measurement, and cervical biopsy if necessary. At the same time, treatment should be actively carried out after the examination and regular review should be conducted in the future.
