Hi, My Girlfriend Made Out. I Did Rub My Genital

Hi,
my girlfriend made out. I did rub my genital on her stomach, near the pubic region but did not ejeculate. But I am afraid that there might have some pre-ejeculation fluid. Can the pre-ejeculation fluid make it way from the pubic region to the vulva and to the vigina? What is the chance of my girlfriend getting pregnant? We were undressed at that point of time.
