they take what is called a speculum and insert it in your vagina. it spreads the walls so they can see inside. it is not really painful, just some pressure. then they use a qtip to scrape some cells off your cervix. this typically does not hurt either. like swabbing your throat. the whole process only takes a couple minutes or less. they will probably look for damage due the sexual assault. I am sorry this has happened to you. take care.
