My Doctor Said I'm Fine — But Is It Perimenopause?

Why does my doctor keep saying I'm fine when I feel terrible?

Because perimenopause is genuinely difficult to catch — and most doctors were never taught how to look for it.

What sounds like a personal failure on your doctor's part is actually a structural one. In a 2019 survey of 183 residents training in family medicine, internal medicine, and OB/GYN at 20 US programs, 93.8% said they considered menopause training important — but fewer than 7% said they felt adequately prepared to manage it.1¹ A 2023 study found that only 31.3% of US OB/GYN residency programs even have a formal menopause curriculum.2²

Read that again: roughly two out of three OB/GYN residencies — the specialty most women see for this — train their doctors without a single required course on menopause.

So when you walk in with hot flashes, broken sleep, mood shifts, and brain fog and you're told your labs look fine, that is not your imagination failing you. It is a system failing you.

What is STRAW+10, and why does it matter for my diagnosis?

STRAW+10 is the standard staging system for the menopause transition — and it uses your cycle pattern and symptoms, not a blood test.

Published in 2012 and endorsed across specialties, STRAW+10 maps the journey to menopause into defined stages with predictable symptom patterns.3³ It works like this:

• Late reproductive stage: Cycles are still mostly regular, but subtle hormonal shifts are already underway.
• Early menopause transition (early MT): You start having persistent variation of seven days or more between consecutive cycle lengths. This is the first official marker — cycles becoming unpredictable.
• Late menopause transition (late MT): You have at least one stretch of 60 or more days without a period. Hot flashes and sleep disruption typically intensify here.
• Final menstrual period (FMP): Not recognized in real time — it is defined in retrospect, after 12 consecutive months without a period.

Each stage has its own set of typical symptoms. The diagnosis of perimenopause — which covers early and late MT — is made by your age, your bleeding pattern, and your symptoms. It does not require a blood result. If your provider is not using this framework, you can ask directly: "Can we use STRAW+10 staging?"

Why can't a blood test just tell me if I'm in perimenopause?

Because the main hormone used for that test — FSH — is far too unstable during perimenopause to give a straight answer.

FSH (follicle-stimulating hormone) is produced by your pituitary gland and rises as your ovarian reserve declines. In a postmenopausal woman, FSH is consistently high. But in perimenopause — the transition — FSH swings dramatically from cycle to cycle, and even within the same month. One draw might look "normal." Another taken weeks later in the same woman might look elevated. That variation is not a lab error; it is what perimenopause actually looks like biologically.4⁴

A single "normal" FSH does not rule out perimenopause. A single "high" FSH does not confirm postmenopause unless you have also been without a period for at least 12 months. NAMS, ACOG, and the Endocrine Society all support making the diagnosis on symptoms for women in their 40s with a classic clinical picture, without requiring a confirming hormone level.4⁴

You may also have heard of AMH (anti-Mullerian hormone), a marker of ovarian reserve. AMH can reflect how much longer your transition might last, but it is not a routine diagnostic tool for perimenopause and is not part of standard clinical guidance.

So what blood work is actually worth getting?

The right tests depend on what you're experiencing — not on "ruling out perimenopause" with an FSH.

Here is what genuinely helps, matched to symptoms:

A pregnancy test when relevant. Irregular cycles in perimenopause can look a lot like pregnancy, and ovulation can still occur even during the transition. If there is any possibility of pregnancy, rule it out first.

For everyone: TSH (thyroid-stimulating hormone). An underactive or overactive thyroid can cause fatigue, mood changes, weight shifts, and cycle disruption that look a lot like perimenopause — and the two can also happen simultaneously. This is a basic, cheap test worth doing.

If your periods are heavy: A complete blood count (CBC) and ferritin (stored iron). Heavy perimenopausal bleeding is one of the most common causes of iron-deficiency anemia, which compounds the fatigue you're already fighting.

If you haven't had a recent metabolic check: Fasting glucose and a lipid panel. Estrogen shifts during perimenopause affect cardiovascular risk markers; this is a good window to establish your baseline.

If you're experiencing fatigue or low mood: Vitamin D and B12. Neither is diagnostic for perimenopause, but deficiencies in both are common and treatable, and correcting them can meaningfully change how you feel.

If you're having palpitations with red flags — chest pain, fainting, or palpitations that wake you from sleep — an ECG or Holter monitor is appropriate. Palpitations without those red flags are frequently hormonal, but the threshold for cardiac evaluation should be low.

If your bleeding pattern is abnormal beyond the expected irregularity: Abnormal uterine bleeding — including very heavy periods, intermenstrual bleeding, or post-coital bleeding — warrants formal evaluation per ACOG guidelines.5⁵ That may mean a transvaginal ultrasound, an endometrial biopsy, or both, depending on your history.

How do I actually push back in the appointment?

Come prepared, and ask specific questions using clinical language — it shifts the dynamic.

Before your appointment, keep a symptom tracker for two to four weeks. Write down your cycle dates, how many hot flashes you experience in 24 hours, your sleep quality, and any mood or cognitive changes. Concrete data is harder to dismiss than "I've just been feeling off."

In the room, try these direct questions:

• "Could this presentation be consistent with perimenopause? I'm [age], and my cycles have changed like this."
• "Can we stage this using STRAW+10 rather than relying on a single FSH?"
• "What would you expect to see on labs that would be worth testing given my specific symptoms?"
• "If you're not comfortable managing this, can you refer me to someone who specializes in menopause?"

That last question is not aggressive — it is a reasonable clinical request. The Menopause Society (menopause.org) maintains a directory of practitioners certified in menopause care (called MSCPs). These are clinicians who have completed additional training and passed a standardized exam in this area. If your current provider is dismissive and you have access to one, they are worth seeking out.

You are not asking for special treatment. You are asking for your symptoms to be taken as seriously as they would be in any other clinical context.
