Early Perimenopause
101
Your periods may still seem regular, but your body is shifting beneath the surface.
You might notice heavier flows, new mood swings, or you might be waking up sweating at 2AM. Even if your labs are "normal," your symptoms are not in your head.
This is often the phase where women are dismissed - but what you’re feeling comes from changing hormones, especially progesterone.
Early Perimenopause
begins when:
Your period comes seven or more days earlier or later than usual, more than once
You’re over 40 (though it can begin earlier)
Symptoms appear even with monthly cycles
What you might notice
PMS that feels more intense
Heavier or longer periods
Interrupted sleep, especially before your period
Unexplained anxiety, mood swings, or emotional reactivity
Many women feel emotionally off during this phase - that doesn't mean you're unstable.
