Is this perimenopause?
Not a diagnosis: a head start. These are the three drivers most worth checking first, based on what the evidence says gets missed most often.
It starts earlier than told
Sleep, mood and cycle changes from the early 40s are often perimenopause, mislabelled as stress.

Iron and thyroid mimics
Heavy cycles drain iron; thyroid disease mimics the whole picture. Test both.
Ferritin, TSH; symptom pattern beats one-off hormone tests
1. Start a two-minute note so the pattern becomes visible.
2. Take the test list above with you so you can explain the pattern clearly.
3. Read the evidence: HRT and Menopause in the UK: The Complete Evidence-Based Guide.
