In Menopause: Symptoms – Common Symptoms of Menopause and Perimenopause: Changes To Your Periods the (United Kingdom) NHS explain:

“The first sign of the perimenopause is usually, but not always, a change in the normal pattern of your periods, for example they become irregular”.2

Perimenopause Menstrual Cycle Changes

In Perimenopause: What Happens At Perimenopause? the (Australian) Jean Hailes for Women’s Health (JH) elaborate on:

Look for A PatternPeriods Pattern

How may I Look for A Pattern with my periods?

The (United States) Mayo Clinic explain:

“To find out what’s typical for you, start keeping a record of your menstrual cycle on a calendar. Begin by tracking your start date every month for several months in a row to identify the regularity of your periods”.4

In Menstrual Cycle: What’s Normal, What’s Not – How Can I Track My Menstrual Cycle? the Mayo Clinic also elaborate on:

“If you’re concerned about your periods, then also make note of the following every month:

  • End date…
  • Flow…
  • Bleeding changes…
  • Pain…
  • Other changes…”.5

Menstrual Calendar

Where may I find a menstrual calendar to keep a record of my periods?

In MenoNotes the North American Menopause Society (NAMS) include:

Pregnant or Not

Is it possible to become pregnant when skipping periods?

Yes. In Menopause: Symptoms & Causes – Symptoms the Mayo Clinic explain:

“Skipping periods during perimenopause is common and expected. Often, menstrual periods will skip a month and return, or skip several months and then start monthly cycles again for a few months. Periods also tend to happen on shorter cycles, so they are closer together. Despite irregular periods, pregnancy is possible. If you’ve skipped a period but aren’t sure you’ve started the menopausal transition, consider a pregnancy test”.6

Health Care Provider

What if I would like help to look for a pattern with my periods?

If you would like help to look for a pattern with your periods, it may be in your best interest to choose to talk to your health care provider about your record. Together you can identify any patterns, discuss your options and if required, agree on who may be the most appropriate health care provider to help you.

In Menstrual Cycle: What’s Normal, What’s Not – How Can I Track My Menstrual Cycle? the Mayo Clinic note:

“Remember, keeping track of your period can help you find out what’s typical for you and what isn’t. If you have questions or concerns about your menstrual cycle, talk to your health care provider”.7

In Periods: When To See Your Doctor the JH also note:

“You should see your doctor if you are worried about your period. For example, if your period patterns change or your symptoms are so painful they stop you from doing things you normally do”.8

In Perimenopause: How Do I Know If Changes In My Periods Are Normal Perimenopausal Symptoms or Something To Be Concerned About? the Cleveland Clinic elaborate on:

“Irregular periods are common and normal during perimenopause, but other conditions can cause abnormalities in menstrual bleeding. If any of the following situations apply to you, see a healthcare provider to rule out other causes.

  • Your periods are changing to become very heavy, or accompanied by blood clots
  • Your periods last several days longer than usual
  • You spot or bleed after your period
  • You experience spotting after sex
  • Your periods occur closer together”.9
