Yes, of course. The cycle length can vary hugely between individuals and from month to month. If you have irregular periods, tracking your cycle to identify patterns and learn when to expect your period is essential. While the follicular phase may take longer sometimes, the luteal phase is usually around two weeks, so you can pinpoint when to expect your period once you’ve noticed telltale ovulation symptoms.  Symptom tracking can help you to make sense of your irregular cycles. A cycle length of between 21 and 35 days is considered normal, but if your cycle length is shorter and longer than this window, it’s worth consulting your OBGYN to see if an underlying health condition may be to blame.
