Hello. To Cut To The Chase, My Girlfriend And I

Hello.
To cut to the chase, my girlfriend and I recently had our first sexual experience. She was giving me a "hand-job". As she was doing it, I was "helping her" do it from time to time by getting my hand on my penis as well. Then, together with lubricant on my hands, I inserted my fingers into her vagina. I am afraid some of my pre-ejaculatory fluid got onto my hand, and from there to her vagina. She is during her ovulation period (deemed the most effective to get pregnant).

Will she get pregnant ?
