Yes, : Yes, if you are concerned about pregnancy, then she should use Plan B if she does not want to be pregnant. There is sperm that is present in pre-cum (pre-ejaculate). Always use a condom to prevent pregnancy or infection. She can also ask her gynecologist about birth control pills, or implantable devices such as norplant, paragard, or mirena (levonorgestrel).
