At 41 it gets called stress. At 46, aging. By 52 someone finally names it, usually years after we could have done something about it.
The problem isn't that perimenopause is subtle. It's that it doesn't hold still. What it looks like at 41 — the cycle shortening by two or three days, the 3am waking, the anxiety that feels chemical rather than situational — looks nothing like what it looks like a decade later. So each version gets explained away by whatever else is happening in your life at the time. Work. Kids. Aging. Something.
By the time it's obvious enough to name, you've usually spent years managing symptoms one at a time instead of managing the cause.
You don't have to wait for the obvious version.
Most women get this list at 52. Send it to someone in her early 40's.
