Yesterday I was doing some foreplay with my girlfriend. During foreplay my penis ejaculated some fluid but not the fluid which comes after orgasm. I touched my penis and hence little bit of fluid comes on my finger. After that I inserted my finger in her vagina but not too much inside. Is there any possibility that she becomes pregnant from this. Her last period ended on 8 or 9th aug 2016 and this foreplay I did on 23.08.2016.
