Normal cycles: Normal cycles come every 21-35 days. A period coming two days earlier than you expected is very common and normal.

Many possibilities : If you have a short luteal phase that can account for what you describe. Certainly whenever your period is abnormal you have to double check that you aren't pregnant.
