Answer
Ovulation occurs around day 16 - 18 after the period begins.  But this presupposes a very regular cycle pattern.  It can vary, so unless you are taking careful watch of the symptoms of fertility, you won't know for sure when ovulation occurs.  But after ovulation until the next period begins, she cannot get pregnant.
