Perimenopause is the transition before your periods stop, and it can begin in your late 30s or 40s, often years before anyone mentions the word menopause. Hormones shift unevenly during this time, which is why the signs can feel random.
Hot flashes get the attention. But many women notice quieter changes first, and assume they’re just stress, age or a busy season of life.
The signs nobody mentions
- Sleep that falls apart. Waking at 3 a.m., night sweats, or not feeling rested after a full night.
- Mood changes. New anxiety, irritability, or a shorter fuse than usual.
- Brain fog. Losing words, forgetting why you walked into a room.
- Skin and hair changes. Drier skin, new breakouts, thinning hair.
- Cycle changes. Shorter, longer, heavier, or more unpredictable periods.
- Lower libido or vaginal dryness. Common and treatable, and rarely talked about.
- Joint aches and weight shifts, especially around the middle.
Why it happens
Estrogen and progesterone don’t decline in a straight line. They rise and dip from month to month, and progesterone often drops first. That unevenness is what makes perimenopause feel so unpredictable.
What can help
The right plan depends on your symptoms, history and goals. It can include lifestyle changes, targeted supplements, or hormone therapy where appropriate. Lab work helps, but symptoms matter just as much, since levels can change day to day.
When to talk to someone
If changes are affecting your sleep, mood, relationships or work, it’s worth a conversation. Always see a provider promptly for very heavy bleeding, bleeding between periods or bleeding after menopause.
