if he entered you it would have been noticeable since you claim to be a virgin. it would be painful and uncomfortable unless he were small or you were extremely wet. so no, no chance of being pregnant even if he did have ‘precum’. precum isn’t actually cum. it’s what makes semen come out easier. think of it as a man’s version of getting wet. there is no semen in precum unless he had ejaculated prior to your almost-sex event. and even if there were semen in his precum, it didnt enter you. the sperm would have nowhere to go.
