My and my girlfriend had protected sex, and continued with intimacy, which led to us having outercourse be my massaging her vagina with my erect penis through her legs from the spooning position. could precum have got her pregnant like this?

Nothing in =: Nothing in = No baby out. That means if no sperm went into the vagina, no baby's coming out of the vagina. The question one has to ask oneself is, "How sure am I that nothing went into her vagina?" If very sure, then no worries. Otherwise, a home pregnancy test gives an accurate result 3 weeks after sex, or 1 week after missing a regular period.
