If you have long periods – you’re bleeding for longer than one week – your period is not normal and this may be a sign that something is going on with you. You may have a reproductive problem, fibroids, cysts, or even something more serious. However, there are exceptions to this rule. For example, if you’re in your 40s and entering perimenopause, or if you’re a teenager who just started having periods, then having a long menstrual period may be normal.
If you have prolonged, heavy periods, you are said to have an irregular menstrual period.
