The situation that you are describing is very unlikely to result in pregnancy.
The fact that there was no actual penetration (or even close to it) and that she was only 3rd day after the end of the period makes this unlikely,
However, stranger things have happened, and if there is any significant delay in the next periods, you can certainly consider getting a urine pregnancy test done,
