Is Pregnancy Possible Without Ejaculating In The Vagina?

Can my girlfriend gwt pregnant after inserting my dry penis in her for like 4 seconds?. Ejaculated like less then an hour ago before that or an hour, we both checked for precum right before, it was completely dry, her vagina was pretty dry too, and thats why i pulled it out halfway in, it hurted and we also had to go. I think the whole process of insterting, it being there, and pulling out was 3 seconds. Is there any chance she could get pregnant? She is starting her semi fertile days today.
