Pre-Menopause

Regular cycles, mid-30s to early 40s

Hormones remain relatively balanced

“PMS feels more intense, but my cycle is still on schedule. I just really don’t feel like myself the week before.”

Subtle shifts might begin, like increased PMS, slight mood changes, or new sleep patterns. These can be early signs of hormonal sensitivity.

Early Perimenopause

Cycle variability begins, early to mid-40s

Hormonal imbalance starts to cause noticeable symptoms

“I’m suddenly waking up sweating at 3AM and crying before my period, but my doctor says my labs look fine.”

Even with regular cycles, you might feel off: disrupted sleep, mood swings, heavier periods, or increased anxiety are common.

Late Perimenopause

Irregular cycles, late 40s

Hormone levels fluctuate dramatically

“My period ghosted me for two months, then came back. I’m bloated and exhausted, and I can't remember easy things.”

You may experience intense symptoms: skipped or prolonged cycles, brain fog, night sweats, weight changes, or joint pain. This is often the most physically and emotionally demanding phase.

Menopause

12 months without a period, typically early 50s and beyond

Hormones stabilize at low levels

“Everyone said things would get easier. But I still can’t sleep, and sex feels so painful these days. I think I'm losing strength, too.”

Some symptoms ease, but others like vaginal dryness, reduced libido, bone density loss, and sleep disturbances - can continue or emerge. This is a critical phase for preventive health and thriving long-term.
