Is there a checklist for perimenopause?

Yes. No single test confirms perimenopause, so guidelines such as NICE NG23 rely on symptoms and cycle changes, especially from age 45. This checklist lets you note your period pattern and symptoms by pathway, then copy a summary to take to your doctor or specialist.

Can a blood test confirm perimenopause?

Usually not. FSH levels swing a lot during perimenopause and are unreliable on hormonal contraception. NICE suggests FSH testing mainly when premature ovarian insufficiency is suspected under 40, with two tests 4 to 6 weeks apart.
