Perimenopause & Irregular Periods: What's Normal

In perimenopause, fluctuating estrogen and progesterone make periods irregular: cycles get shorter or longer, flow changes, and periods may be skipped. This is expected. But very heavy bleeding, periods closer than 21 days apart, bleeding between periods, or bleeding after sex should be checked by a doctor.

What's normal in perimenopause

Irregularity is the hallmark of this transition.

  • Cycles that shorten, lengthen, or vary month to month.
  • Lighter or heavier flow than you are used to.
  • Skipping a period, then having one return.

When to see a doctor

Some bleeding changes are worth medical attention even during perimenopause.

  • Very heavy bleeding, soaking through protection hourly, or large clots.
  • Periods closer than 21 days apart or lasting more than seven days.
  • Bleeding between periods, after sex, or after 12 period-free months.

Frequently asked questions

Is it normal to skip periods in perimenopause?

Yes. Skipped and irregular periods are one of the most common signs of perimenopause as ovulation becomes erratic. Once you go a full twelve months with no period, you have reached menopause.

How can I track a cycle that keeps changing?

Focus on logging symptoms and any bleeding rather than predicting exact dates. Tracking flow, mood, sleep, and hot flashes helps you and your doctor understand your pattern and spot anything unusual.
