HI!
I think that chances are low--since she was so late in her cycle--day 24 if I understand everything correctly--and since you didn't ejaculate. The chance is not zero however.
Don't forget about Plan B--the morning after pill--although its too late in this instance.
If she has a
normalNormal saline flush period within the next week or so, I think you are in the clear. If more than two weeks pass and no menstrual period, then it is definitely time to take a test.
By the way, the breast tenderness, etc. is almost certainly NOT due to a pregnancy caused by intercourse only 8 days ago. It takes a minimum of 10 days for any pregnancy-related symptoms to occur.
Good luck!
