It is unlikely that your girlfriend’s nausea and vomiting is being caused by a pregnancy that was conceived one week ago. Morning sickness does not usually occur until the 6th week of pregnancy. Most likely, she was simply ill. The cramping she is experiencing now may be a sign that her period is about to begin.
However, even when a man does not ejaculate inside the vagina, pregnancy is still possible because of pre-seminal fluid (also called pre-ejaculate). Pre-seminal fluid leaks out of the penis prior to ejaculation. Sometimes this fluid contains sperm that is left in the urethra from a previous ejaculation. If a man urinates between ejaculations before having sex again, it will help clear the urethra of sperm and may increase the effectiveness of withdrawal. Therefore, if you urinated between your last ejaculation and the incident that you described, the risk of pregnancy is slim.
