You're in your mid-40s and suddenly your periods are all over the map. One month it's a flood, the next it's barely a trickle. You're waking up drenched at 3 a.m., and your patience has evaporated. Sound familiar?

Welcome to perimenopause — the transition years before menopause when your ovaries gradually produce less estrogen. It typically starts in your mid-40s and lasts about four years on average, though it can stretch up to eight. The challenge? Knowing which symptoms are normal and which ones need a doctor's attention.

This checklist breaks it down so you can stop guessing and start acting.

The full symptom picture

Perimenopause affects everyone differently, but most people experience at least some of these changes:

Irregular periods — cycles get shorter, longer, heavier, or lighter
Hot flashes and night sweats — sudden waves of heat that can disrupt sleep
Sleep problems — trouble falling or staying asleep, often tied to night sweats
Mood changes — irritability, anxiety, or low mood that feels different from your baseline
Brain fog — trouble concentrating or remembering things
Vaginal dryness — discomfort during sex and increased urinary urgency
Weight gain — especially around the midsection
Joint pain and headaches — often worse than before

The NHS notes that symptoms can last seven to nine years total and may shift over time — hot flashes might fade while mood issues take their place.

When it's normal vs. when to call

Here's the practical rule: most perimenopause symptoms are normal. But some patterns signal something else entirely.

Call your doctor if you experience any of these:

Bleeding that's heavy enough to soak through a pad or tampon every one to two hours
Periods that last more than seven days
Bleeding or spotting between periods
Bleeding after sex
Periods that occur less than 21 days apart
Any vaginal bleeding after you've gone 12 months without a period

The American College of Obstetricians and Gynecologists is clear: these patterns are not normal and need evaluation to rule out fibroids, polyps, or other conditions.

Your perimenopause action checklist

Print this. Save it. Bring it to your next appointment.

Track your cycle. Note start dates, duration, and flow level (light / moderate / heavy / very heavy). Apps work, but a paper calendar is fine.
Log your symptoms. Write down hot flashes, night sweats, mood shifts, and sleep quality. Patterns become obvious after two weeks.
Check your sleep. If night sweats wake you more than three times a week, mention it. Sleep disruption is one of the biggest quality-of-life hits in perimenopause.
Review your mental health. Anxiety and depression are common in perimenopause. If your mood feels off for more than two weeks, say something.
Assess your bleeding honestly. If you're changing protection every hour, that's not "heavy for you" — that's a medical conversation.

Treatment options worth discussing

If your symptoms are disrupting your life, you have options. Hormone therapy (systemic estrogen) is the most effective treatment for hot flashes and night sweats. Vaginal estrogen can help with dryness and urinary symptoms. Non-hormonal options like certain antidepressants or fezolinetant also work for hot flashes.

The Mayo Clinic recommends checking in yearly with your provider to make sure your treatment still fits, since your needs change as you move through the transition.
