This is also a common fix for some women. Go exercise for a while. Go for a run or a swim. It almost always works for me, whether I want it to or not.
Don't worry too much about it though, there are times that you can go up to 4 weeks late and then just start. Periods are unpredictable because your hormone levels have to reach just the right place b4 anything will start.
The only time you should be concerned is if you think you could be pregnant, or if it is a consistent problem. In both cases go see your doctor.
