There is no way she is pregnant. As has been said, you would need to get cum into her vaginal canal. Her simply touching her cum with her hand would have 0 impact. Even if she'd immediately stuck that finger up her vagina, the chances of that small amount of cum some how propelling upwards into her uterus are miniscule.

I would strongly recommend researching how pregnancies occur if you're engaging in any kind of sexual activity in order to become educated and be able to make safe choices and to also minimize unnecessary fears.
