The chances are slim to none. If you washed your hands, they were probably clean enough before you touched her. Even so, semen dries up after a short time and becomes useless (for it's intended purpose). So the chances really are very low. If you're still concerned, she could take a morning after pill (if it's been less than three days since) or else you can wait until her next period is due. After two weeks, she can take a pregnancy test if you're still worried but you chances are low.
