Very unlikely but could happen.. There would have also had to have been alot of semen on her hand for that to happen... I would have her just wait until her next period and see what happens.
Very unlikly this would happen but there is a chance if her cervial mucus was actually good. Sperm really has to be up close to the cervix for this! How does she know she ovulated though, just wondering? Sperm (usually girl swimmers, they live longer and swim slower) can live up to 5 days in good quality cervical mucus. But did you know that spit kills sperm and most lubrications do as well.
Like smjmegkg said I would not stress about it. If she is not wanting to get pregnant which it sounds like she should not with this person then she needs to be more careful! Hope this info helps ease her mind though
Unlikely that she is pregnant, but still possible. Tell her not to stress, and to wait until her period is due and test then if she is late.
The possibilities are low that your friend is pregnant. There would have needed to be fertile quality cervical mucus to keep the sperm mobilized during those days and he would have needed strong swimmers to last those few days. Otherwise the vagina makes for an unwelcome enviroment to sperm due to the pH levels to ward off bacteria.
it would be very unlikely
