Menstrual Problems

Regular periods are a sign that your body is working normally. You should have regular periods unless you are pregnant, breastfeeding, postmenopausal, or have a medical condition that causes your periods to stop. Irregular, painful, or heavy periods may be signs of a serious health problem. Irregular periods also can make it harder to get pregnant. Your doctor can work with you to help get your periods more regular.

Your periods are considered irregular if your menstrual cycle is shorter or longer than average. This means that the time from the first day of your last period up to the start of your next period is less than 24 days or more than 38 days.

Your periods can also be irregular if your cycle length varies by more than 20 days from month to month.10 An example would be your cycle jumping from a normal 25-day cycle to a 46-day cycle the next month and then back to a 25-day cycle the following month.
