Precautions for electronic colposcopy: 1. It is best to have colposcopy 3-7 days after menstruation because the cervical discharge is less at this time and the field of view is clearer. 2. 48 hours before the colposcopy, no intercourse, no sitz bath, no vaginal plugs, and no vaginal douching. 3. 24 hours after the colposcopy, come to the hospital to remove the vaginal gauze. 4. Do not take a sitz bath or have sex for half a month after the colposcopy. 5. It is recommended to wash the vulva with water twice a day to keep it clean and avoid pathogenic infections. If the vaginal bleeding is high after colposcopy, you must go to the hospital to give the appropriate treatment.
