I was fooling around with a girl, and though I didn't really intend to, I entered her. I was only in there for like 20 to 40 seconds (hard to tell) and I never ejaculated. In fact, I didn't ejaculate the entire night.

I'm looking up statistics on the pulling out contraceptive method, but that's really not what this was. I'm also aware that pre-ejaculate can sometimes cause pregnancy, and although the possibility seems extremely low when both factors are combined, I'd like to confirm this as well as possible.

Thank you.
