Perimenopause symptoms — the women's checklist (and what to actually test).
Perimenopause is the 4–10 year transition before your last period — usually somewhere between 35 and 55. Hormones don't decline in a straight line; they swing. Many women feel the swings years before any cycle change shows up.
This page is the symptom checklist our team runs with every Her Form perimenopause client, plus the biomarkers that actually clarify what's going on, when to test, and how the Perimenopause Package fits. a women's-health specialist who has worked with Her Form since launch — is available for an optional 1:1 consult.
The perimenopause symptom checklist
- ✺Cycles getting shorter, longer, heavier or irregular
- ✺Night sweats, hot flushes or new temperature sensitivity
- ✺Sleep that fragments at 2–4am — even when you're exhausted
- ✺Mood shifts: new anxiety, irritability, low mood or tearfulness
- ✺Brain fog, word-finding lapses, dips in focus
- ✺Lower libido, vaginal dryness or painful sex
- ✺Joint aches, stiffness — especially mornings
- ✺Weight settling around the middle despite no diet change
- ✺Skin changes — dryness, breakouts, thinning hair
- ✺Heart palpitations, especially around your period or at night
What's happening hormonally
Progesterone falls first. Ovulation gets less reliable, so the corpus luteum makes less progesterone. This is why sleep, calm and PMS often get worse before any cycle change appears.
Estradiol swings — wildly. It can spike (breast tenderness, heavy periods, headaches) then crash (hot flushes, brain fog, low mood) in the same month. FSH starts climbing as the brain works harder to recruit a follicle.
Thyroid often gets dragged in. Roughly 1 in 8 women develop a thyroid issue around perimenopause; symptoms overlap enormously (fatigue, weight, hair, mood). This is why TSH and antibodies belong in every perimenopause panel.
Cortisol and insulin tilt. The hormonal stress on the body raises baseline cortisol and reduces insulin sensitivity — which is why belly weight, sleep and energy all shift together.
When in your cycle to test
If you still have a cycle: day 2–5 for FSH, LH and estradiol. Day 21 (or 7 days post-ovulation) for progesterone. AMH, TSH, free T3/T4 and thyroid antibodies can be drawn any day.
If your cycle is irregular or has stopped: test whenever — but expect two snapshots over 3 months to read trend, not just a single number.

When in my cycle should I test for perimenopause?+
Day 2–5 of your cycle (if you still have one) is the cleanest window for FSH, LH and estradiol. Progesterone is most informative 7 days after ovulation — roughly day 21 of a 28-day cycle. our health specialists reviews your symptom timeline before booking so the draw lands on the right day.
FSH was 'normal' but I still feel terrible — what now?+
Perimenopause FSH fluctuates dramatically month to month. A single 'normal' result misses early-stage perimenopause more often than not. Pair FSH with estradiol, AMH, TSH and progesterone over the right cycle day, and read symptoms alongside the numbers — that's how our health specialists builds the picture.
Can I test perimenopause on birth control or HRT?+
Combined oral contraceptives and HRT mask your true FSH, LH and estradiol. AMH, TSH and thyroid antibodies stay reliable. If you're on the pill or HRT, we'll tell you which markers are actionable and whether a brief pause makes sense.
How is the Perimenopause Package different from a GP blood test?+
Most GP panels run TSH and FSH and stop there. The Her Form Perimenopause Package runs 31 markers — full sex hormones, thyroid (TSH, free T3, free T4, antibodies), adrenal, cardiometabolic and bone — with a written specialist review by our health specialists and a women-specific protocol, not a 'within range, see you in a year'. Robyn is available for an optional 1:1 consult.
How long does it take to get perimenopause test results?+
Typically 7–14 working days from the home draw. You receive a written specialist review from our health specialists alongside your results — not just numbers on a printout — plus the option to book Robyn for an optional 1:1 consult if you want to talk through next steps.
