Tracking low mood in perimenopause

Flatness, heaviness, joy going quiet — low mood in the transition can be new, or an old tendency getting louder. Mood symptoms in perimenopause are common, real, and treatable, and they deserve dated evidence rather than self-blame.

Why it shows up now

The hormonal turbulence of perimenopause is a recognized window of mood vulnerability, particularly for women with a history of premenstrual or postnatal mood changes. Sleep disruption from night symptoms stacks on top.

How to track it

What a useful record looks like

Weeks of dated mood entries, phase-tagged and shown against sleep, is the difference between 'I've been feeling down' and a record a clinician can classify and act on.

Questions

Is this perimenopause or depression?

That's a clinical judgment, and the honest answer is that a dated record is what makes the judgment possible — mood that rides your cycle looks different from mood that doesn't. Thyroid problems can mimic it too, which is why TSH is on the checklist. Bring the record; let a clinician do the classifying.

Does tracking mood actually help?

It doesn't treat anything — Perity never claims to. What it does is preserve the shape of the thing: how often, how deep, what rhythm. Treatment decisions get made faster and better on top of that record.
