i used my fingers instead of my penis now she is a day late

oK Now let me try and under stand this.. You didn't have sexual intercourse? Meaning you didn't penatrate her with you penis or anything? You just finger banged her.. Right.. If thats the story then no she can't get pregnante from being banged.. With her being late it could be caused from stress.. There are alot of reasons why a girl can be late for her period..I hope that helped a little!
