yes. you should be worried and ashamed of yourself to put your girlfriend at risk. if you are having unprotected sex even unplanned unprotected sex you are both taking the risk of pregnancy since penile secretions prior to an ejaculation can have sperm present. use a condom and stop having risky sex play. if your girlfriend does not have her regular period she will need to get a pregnancy test. if the pregnancy test is positive your level of worry will take a new high.
