Why Do I Have Bleeding After a Vaginal Ultrasound?

Bleeding after vaginal ultrasound, excluding menstruation, may indicate the presence of some gynecological diseases, such as cervical erosion, cervicitis, etc. Women should relax during vaginal ultrasound examination to ensure more accurate results. If a pregnant woman experiences bleeding after vaginal ultrasound, she should promptly undergo examination to prevent miscarriage.

Vaginal ultrasound involves placing an ultrasound probe within the vagina, which has a high diagnostic rate for diseases in the accessory areas. It is often used for vaginal ultrasound examination, especially for those who cannot hold their urine or have thick abdominal fat, and does not cause vaginal bleeding. Diseases such as vaginitis, cervical lesions, and endometrial lesions can cause abnormal bleeding symptoms. Therefore, it is important to determine the source of the bleeding during gynecological examination before considering treatment options.

The duration of menstrual cycles can vary, and the amount of bleeding can also be inconsistent. In severe cases, bleeding can be several times greater than normal menstrual bleeding, even leading to shock, while in mild cases, bleeding may be continuous and prolonged. This is often due to instability of ovarian function during these periods, resulting in anovulatory bleeding. Patients usually experience a period of amenorrhea before experiencing uterine bleeding, which is often excessive or prolonged, and then turns into irregular or persistent uterine bleeding.

For pregnant women with a regular menstrual cycle, the appearance of vaginal bleeding after amenorrhea should raise concerns about preterm labor. In cases of threatened miscarriage, vaginal bleeding is usually minimal, accompanied by no or mild lower abdominal pain, and may be accompanied by early pregnancy symptoms. Examination may reveal that the cervix is closed, the size of the uterus is consistent with the menstrual age, and blood and urine pregnancy tests are positive. However, if the fetus has already died or the cause of miscarriage has not been eliminated, vaginal bleeding may increase accompanied by uterine cramping pain and dilation of the cervical os, indicating inevitable miscarriage.
