it is highly HIGHLY unlikely, first off it is not likly that she was ovulating anywhere around the time and secondly it is highly unlikely to get pregnant from "fingering" someone especially if your hands where dry

if its been less then 72 hours and you are really worried get plan b, if its been more then wait until her next period and take a test, dont stress that can cause her period to be late too.....but like i said unlikely

I personally highly doubt that she is pregnant! If this was within the past 72 hours I agree with Idony, go and get plan B to put your mind at ease. Good luck to the both of you!
