My girlfriend gave me a blowjob, kissed me, and i then performed oral sex on her. what are chances of her getting pregnant if this happened around ovulation?

Pregnancy unlikely: Pregnancy unlikely in such a scenario. That said, couples who engage in penis activities, near a vagina, should always be ready for a cute, surprise baby. If a woman has her regular NORMAL menstrual period, then she is not pregnant. If she still thinks she is pregnant, then doing a urine pregnancy test the week after missing her period, or 3 weeks after having sex, should give an accurate result.
