When to see a doctor about your hormones, and what to bring.
The short answer to when to see a doctor about hormones: when a symptom has lasted more than a couple of cycles, when it is getting in the way of your life, or when something has changed and you cannot explain it. You do not need to be sure it is hormonal before you book. Working that out is the doctor's job, and a good appointment is as much about the story you bring as the tests that follow.
This article is about making that appointment count: which symptoms are worth raising, what a hormone doctor (whether that is your GP or a women's health doctor) will want to know, and a short list of things to bring.
Symptoms that are worth a conversation
Hormones touch almost every system, so the list is broad. None of these means something is wrong, but each is a reasonable reason to be seen.
- Cycle changes. Periods that have become irregular, much heavier, much lighter, closer together, further apart, or have stopped for three months or more when you are not pregnant.
- Trying to conceive. Twelve months of trying without success, or six months if you are 35 or older, is the usual point at which guidelines suggest assessment. Earlier if your cycles are irregular or you have a known condition.
- Skin and hair. New or worsening acne as an adult, hair growth on the face or body, or thinning hair on the scalp.
- Energy, mood and sleep. Persistent tiredness, low mood, anxiety, irritability or broken sleep that does not have an obvious cause.
- Temperature and body changes. Hot flushes, night sweats, weight change without a change in habits, breast tenderness or milky nipple discharge.
- Pain. Period pain that stops you doing normal things, pain with sex, or pelvic pain outside your period.
Some things should not wait for a routine appointment. Very heavy bleeding that soaks through protection hourly, severe pelvic pain, bleeding after menopause, or bleeding in pregnancy all need prompt medical attention.
Why timing your visit matters
Many hormone levels change across the cycle, so when you are seen, and when blood is drawn, shapes what the numbers mean. FSH, LH and oestradiol are most informative in the first few days of a period. Progesterone is checked about a week before the next period is due to confirm ovulation. AMH and thyroid function can be checked on any day. If you are on hormonal contraception, several of these will read differently, and a doctor will factor that in. Our article on contraception and hormone tests explains why.
You do not need to get the timing perfect before you book. But if you can, note where you are in your cycle on the day of the appointment and on the day of any blood test. It saves a repeat draw later.
What a hormone doctor will ask
Expect the first part of the consult to be questions, because the history narrows things down more than any single test. A doctor will usually want to know:
- Your cycle. How long it is, how regular, how heavy, how painful, and when it last changed.
- Your reproductive history. Pregnancies, miscarriages, contraception past and present, and whether you are trying to conceive or planning to.
- Your symptoms over time. When each one started, whether it comes and goes, and what makes it better or worse.
- Medicines and supplements. Everything, including over-the-counter products, because several affect hormone results or mimic hormonal symptoms.
- Family history. Early menopause, thyroid disease, PCOS, diabetes, or clotting problems in close relatives.
- Sleep, stress, weight and exercise. Not to judge, but because each of these moves hormones, and because heavy training or significant weight change can stop periods on its own.
What to bring
You do not need to arrive with a dossier. A few notes make a real difference.
- A cycle log. Even three months of dates from a period-tracking app, with notes on flow and pain, is gold. If your cycles are irregular, the pattern of irregularity is itself useful information.
- A symptom timeline. A few lines on when things started and how they have changed. Photos can help for skin or hair concerns.
- Previous results. Any blood tests, ultrasound reports or specialist letters from the last couple of years, even if they were "normal". Trends across time are often more telling than one result.
- Your medicine and supplement list. Names and roughly when you started each.
- Your questions. Write down the two or three things you most want answered. Appointments go quickly and it is easy to walk out having forgotten the main one.
What happens after the consult
Depending on the story, the doctor may examine you, order blood tests, arrange an ultrasound, suggest a period of tracking before testing, or refer you on. If tests are ordered, ask what each one is for and when to have it drawn. If nothing is ordered yet, ask what would change that. A doctor who wants to watch and wait for two cycles is usually being careful rather than dismissive, and it is fine to ask them to explain their thinking.
Once results are back, a follow-up conversation is where the real value sits. A number in isolation, whether high, low or in range, means much less than that number read alongside your history. If you would like to see how a set of results is presented, our sample report shows the layout KnowLuna uses.
Your GP, a specialist, or a women's health doctor
Your GP is the right starting point for most of the symptoms above, and when a GP orders tests for a clinical reason, Medicare usually rebates them. Some GPs have a particular interest in women's health; it is reasonable to ask when booking. A gynaecologist or endocrinologist is usually reached by referral when a specific condition needs specialist input.
KnowLuna sits alongside those options rather than replacing them. If you already have a doctor's request, you can use it and pay the test-only price. If you do not, a KnowLuna women's health doctor can take your history, request the relevant tests, and explain the results with you in a 20-minute video consult. Either way, the tests are self-pay and not rebated, and your results can be shared with your GP so nothing gets lost between doctors.
Common questions
How do I know if my symptoms are hormonal or something else?
Often you cannot tell from symptoms alone, and neither can a doctor without a history and sometimes tests. Tiredness, mood changes and weight change all have hormonal and non-hormonal causes. That is why the conversation comes first and the tests follow.
Should I stop the pill before seeing a doctor about my hormones?
Not without talking to a doctor first. Hormonal contraception does change what several tests show, but there are ways to work around that, and stopping has its own consequences. Mention it at the appointment and let the doctor advise.
Is it worth going if my last blood test was normal?
Yes, if the symptoms are still there. A normal result narrows the list rather than closing it, and timing, contraception or the particular tests chosen can all affect what "normal" meant. Bring the old result so the doctor can build on it.
Can I see a doctor about hormones through KnowLuna without a GP referral?
Yes. A KnowLuna women's health doctor can request tests and explain results without a referral. Our guide to hormone tests without a GP referral covers how that works.
