If regular periods..: If periods are regular, meaning they are the same number of days apart, then one can count the number of days from the first day of bleeding of one period, to the first day of bleeding of the next period. In this case, january 3 to january 28, which is 25 days long. If regular, then her cycle each time is 25 days, give or take a day. Just add 25 days to january 28 to estimate the next period.
