the other day, my girlfriend and i were fooling around, and my penis touched her labia (it wascloser to the clit, not the vagina). i pre-ejaculated before this, but wiped off my penis with my hand, and i only touched/poked her for a second, and she was dry where i touched her. i am wondering, given that there was no medium for the (little to no) sperm in the pre cog (i urinated before messing around and didn't masturbate that day) to travel to the vagina and into the correct places to fertilize the egg, is there even a chance that she could be pregnant?
