Patient: My sister, had her boyfriend home last night and they were naked. He didn’t pre-cum or cum but her hands were on his dick. She then apparently went to the washroom and apparently chummed herself. She also said that she had not washed her hands and has stuck her finger in her vagina. They didn’t have sex but she is worried about being pregnant, she is currently taking ponister 2 within 24 hours. What chance does she have to be pregnant?
