In brief: Cycle varies.
The average length of a menstrual cycle is 28 days from the start of one period to the start of the next.
It is due to the cyclical production of hormones in the body. However, the cycle length can vary by a few days from month to month due to variation in the hormone release.

In brief: Maybe normal, or not
Normal periods can come anywhere from every 21 days to every 35 days, so even if your period doesn't come at exactly the same date every month, you could still be having normal menstrual cycles.
But if your cycles are a lot longer or shorter, or if they are irregular and unpredictable, there could be many causes and you might consider checking with your doctor.
