A discharge that looks like snot after a tubalogram may be vaginal discharge, or runoff of contrast material. Tubal imaging involves injecting a contrast medium into the uterine cavity and fallopian tubes through a catheter, and then checking the patency of the uterine and tubal cavities by X-ray or ultrasound. After the examination, some of the contrast agent injected into the body will pass through the uterine cavity and the cervical canal, a channel, and be discharged out of the body, and there will be a visible discharge out of the body. Tubal imaging is usually performed 3-7 days after menstrual cleansing, and if the examination time is close to the day of ovulation, the vaginal secretion itself will gradually increase, and the appearance of snotty discharge may be its own vaginal secretion, and if there is no other abnormality, there is generally no need to worry. If there is snot-like discharge, accompanied by odor, color change, vulvar itching, pain, etc., consider vaginitis or endometritis, it is recommended to consult a doctor in time to identify the cause, and actively treat the symptoms. Pay attention to personal hygiene, keep the vulva clean and dry, and change clothes frequently.
