hi once it has reached the womb 3 days it can live for up to 7 days max. what she needs to do if she keeps a diary with her period dates in work from that day one is the first day of her cycle day 14 is ovulation day( give or take a day) up to when her period day starts again so who ever it was she can work it out from that. do hope this helps her and you. good luck
