Is Pregnancy Possible Without Sexual Intercourse?

Hello doctor,
Just recently, I gave my boyfriend oral sex and he had some cum on his hands afterwards, I swallowed a little of his cum but not all, afterwards he washed his hands with soap and fingered me a little on the other hand, through my underwear. What is the chance of me becoming preg? My stomach has been feeling upset for the past 3 days &I'm very scared. Please reply
