a change to your periods. They may happen more often

First Sign of Menopause

What is usually the first sign of menopause?

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

“One of the first signs of perimenopause is usually a change to your periods. They may happen more often or less often, and bleeding may get heavier or lighter. Eventually, you stop having periods altogether”.2

Perimenopause Menstrual Cycle Changes

What are some menstrual cycle changes during perimenopause?

In Menopause: How Do You Know You Are In Perimenopause? the (Australian) Jean Hailes for Women’s Health (JH) explain on:

“The most reliable sign you are in perimenopause (or you are ‘perimenopausal’) is if your menstrual periods have become:

  • Irregular
  • Shorter or longer than usual
  • Lighter or heavier than usual
  • Absent for a few months”.3

In Can Perimenopause Cause Your Periods To Be Closer Together? updated on 22 May 2026, the author elaborates on:

“During perimenopause your periods may become:

  • Irregular…
  • Closer together or further apart…
  • Absent…
  • Heavy…
  • Light…
  • Short or long…”.4

Look for A 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”.5

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…”.6

In Heavy Periods: When To Get Medical Advice the (Scottish) NHS Inform explain:

“It can be helpful to keep a note of your period dates and symptoms using a calendar, a diary or an app. You can then discuss this with your doctor who can decide if any tests or treatments might be needed.

If you’re seeing your doctor, there are some useful pieces of information to think about beforehand:

  • The first day of your last period (when it started)
  • How many days your period usually lasts
  • What was the shortest time between your periods (from the first day of one period to the first day of the next)
  • What was the longest time between your periods (from the first day of one period to the first day of the next)
  • How often you need to change your period products on a heavy day
  • If you are over 25, when you had your last smear test”.7

Menstrual Calendar

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

The Menopause Society’s website (formerly the North American Menopause Society) includes:

Menstrual Calendar

Pregnant or Not

Is it possible to become pregnant when skipping periods?

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

“Skipped periods during perimenopause are common and expected. Often, menstrual periods skip a month and return. Or they skip a few months and then start monthly cycles again for a few months.

Period cycles tend to get shorter in early perimenopause, so periods are closer together. As menopause gets closer, periods get farther apart for months before they end.

You can still get pregnant during this time. If you’ve skipped a period but aren’t sure it’s due to menopause, think about taking a pregnancy test”.8

Health Care Provider

What if I would like help with my periods pattern?

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”.9

In Perimenopause: Symptoms and Causes – How Can I Reduce My Risk of Perimenopause Complications? the Cleveland Clinic elaborate on:

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

  • Your periods become very heavy, or contain large blood clots
  • Your change pads or tampons every one to two hours
  • Your periods last several days longer than usual
  • You spot or bleed between periods
  • You bleed after sex
  • Your periods occur less than 21 days apart”.10
