You should not have intercourse for three days before the cervical screening, and you should not apply vaginal medication. The cervical screening will remove the cervical shed cells, so if you have intercourse before the cervical screening, it may affect the test results. You should not have intercourse within one week after cervical screening because there will be some damage to the cervical cells during the screening and a small amount of bleeding will occur, which will take about a week to heal completely. After cervical screening, you should pay attention to personal hygiene and wash your perineum every day to avoid gynecological diseases. If there are abnormalities in the cervical screening, further colposcopy and cervical biopsy should be performed if necessary to exclude cervical precancerous lesions. It is best for women to have regular cervical screening after having sex to prevent cervical cancer.
