Is Pregnancy Possible Without Sexual Intercourse?

hello. three days ago my boyfriend was touching and playing with his penis then he figured me even though he hadn t cum on his hand. i didn t think about it until later that I shouldn t have let him do that. I m pretty sure there was nothing on his finger. i has my period three days later and read online that it could be vaginal bleeding (early sign of pregnancy). I think I am stressing out too much and overthinking it but could I be pregnant? (sorry if you found any of the language used offensive, I am a young teen).
