When is my next period? I'm lost!

Well the time of your next period depends on when your periods before this were? I mean before February. But if you look only at you period in February, your next one should be anywhere from 25 to 30 days. But there are number of things that can make your period to be late - even worrying about possible pregnancy or completely unrelated stress can make your period late for weeks. But its hard to say anything just by the date of one period.
