By the time you are in your 40s, you already have a good sense of what is your ‘normal’. So any changes from your typical pattern can be a sign that your body is going through something. At this age, irregular periods – periods too often, or missed periods – are most likely caused by perimenopause.
Do you need to see a doctor for irregular periods in your 40s? Yes. The changes in your periods could be a sign of something else too. If you feel like your period changes are affecting your daily life, or there are other symptoms as well, you should see a doctor for a checkup.
