Home > MyFORM® Female Hormone Mapping
The only test in the World that maps all four hormones across your whole cycle.
Your hormones tell a different story every day of your cycle. Most tests only listen on one.
MyFORM® Female Hormone Mapping is the only blood test in the world that tracks how your oestrogen, progesterone, FSH and LH move across your entire menstrual cycle.
If you've ever felt something is off but couldn't explain it, you're not imagining it. Your hormones rise, fall, surge and respond to each other in a pattern - and a single blood test on a single day can't show you why. MyFORM® was built to show you the whole picture.

Is MyFORM® Hormone Mapping right for you?
Your hormones influence far more than your cycle. They affect your energy, your mood, your skin, your bone health, your heart and your brain. If something feels off and you suspect your hormones may be involved, understanding how they are moving across your cycle is where the answers begin.
Why standard hormone tests are not enough
Your hormones follow a precise pattern across your cycle. A test taken on one day shows you one point on that map.
The standard hormone blood test, typically taken on day 2 or 3 of your cycle, measures oestrogen, progesterone, FSH and LH at a single moment. What it cannot show is whether those four hormones are following the pattern expected of a healthy cycle.
What a day 3 test cannot tell you
Whether your oestrogen rose correctly across the follicular phase. Whether your LH surged at the right time and at the right level. Whether your progesterone rose to the level associated with ovulation occurring. Whether the overall pattern of all four hormones is following the shape associated with a healthy ovulatory cycle, or whether it shows patterns that warrant further investigation.
That is not a failure of your GP. It is a limitation of the only test that has been available. Until now.
MyFORM® gives you the full picture of how your hormones are moving. Not just a moment in it.
MyFORM® Hormone Mapping is the only blood test in the world that measures all four of your key hormones across your whole cycle. Two carefully timed samples, taken a week apart on day 14 and day 21, capture how your oestrogen, progesterone, LH and FSH are rising, falling and responding to each other in a way that no single-day test can.
The science behind your result
MyFORM® does not simply join the dots. Your results are processed through mathematical algorithms that model how your four hormones interact and fluctuate against the expected healthy pattern for a normal cycle. That is what makes your personalised hormone graphs reliable and what makes your report unique to you rather than a comparison against a population average
Your FORM score
Every MyFORM® report includes your personal FORM score, a measure of how well your ovaries are responding.
What you receive is not raw data and it is not a population average. It is your own personalised hormone graphs for each of your four hormones, a report written specifically for you in plain language, and clear next steps that are actually yours to take.
Want to see what your report looks like?
View a sample MyFORM® report.Simple to do at home. Designed to fit around your cycle.
MyFORM® uses two small finger-prick blood samples collected at home, a week apart. Everything you need arrives in one kit and both samples are posted back to an NHS-accredited lab in the pre-paid envelope provided. When you order, you tell us your average cycle length. Our algorithms, developed against established clinical hormone data, use that information to personalise the interpretation of your hormone map to your unique cycle.
Order your kit
Posted to you with everything you need for both samples including full instructions.
First sample
Take your first sample on day 14 — A finger-prick sample at home, plus a short symptom questionnaire connecting your biology to your symptoms from the start.
Post sample
Post sample 1 and we remind you when to take sample 2 - Once you log your day 14 sample we send a reminder of exactly when to take your day 21 sample. No guesswork, no calendar management.
Secondary sample
Take your second sample on day 21 - Another finger-prick at home plus a second set of symptom questions. Together the two samples give MyFORM® everything it needs to map your full hormone pattern.

Frequently asked questions
This is what our customers ask us about the most. For more information, try our help centre.
Do I have to take the test during the same menstrual cycle?
Yes. Both blood samples must be taken on day 14 and day 21 of the same menstrual cycle.
What do I do if my day 14 or day 21 falls on a Fri-Sun?
If your day 14 or 21 falls on a Friday, we recommend you collect your sample the day before. If your day 14 or 21 falls over the weekend, collect your sample on the following Monday and remember to post in a priority post box in time for that day’s collection.
Do I need to adjust the test days if my cycle is longer or shorter?
No adjustments needed. Our smart algorithm automatically adapts to the length of your cycle. It’s important to stick as close as possible to day 14 and day 21 for accurate results, even if your cycle doesn’t follow the average pattern.
What will the report tell me?
Your report will indicate if your symptoms are likely to be due to perimenopause.
You’ll get a detailed, personalised report with next step actions from an endocrinology expert. The report will tell you:
- If your symptoms are likely due to perimenopause
- Graphs indicating how each hormone fluctuates across your unique cycle
- Your FORM – ovarian response – score indicating how well your ovaries are responding to your control hormones – an indicator of perimenopause
- Personalised ranges for each of the 4 hormones tested on day 14 and day 21
- Confirmation if ovulation has occurred
- Clear next steps and actionable advice
Why can’t I take this test if I’m taking a hormonal contraception or HRT?
Any hormonal contraception or HRT will mask your natural hormone levels. This product has been specifically designed for those who have naturally occurring cycles. If you are using a copper coil you are able to take this test.
What are the 34 symptoms of perimenopause?
Perimenopause comes with a host of psychological and physiological symptoms. The most common symptoms are listed below. You can find out more about each symptom and more about perimenopause in our guide to perimenopause and menopause.
- Irregular periods
- Vaginal dryness
- Increased need to urinate and UTIs
- Breast soreness

How long does perimenopause last?
On average, perimenopause typically lasts up to 10 years[1], but it can vary between women. For some women, perimenopause might last only a few months, while for others, it can extend for more than a decade.
Perimenopause ends when you’ve gone 12 consecutive months without a menstrual period, marking the onset of menopause.

How to test for perimenopause
The best way to test for perimenopause is to track your symptoms and have your blood tested. MyFORM® is the only at-home blood test in the world designed to map the hormone patterns associated with perimenopause, measuring all four key reproductive hormones across your entire menstrual cycle using two timed blood samples rather than a single snapshot. It provides a detailed report into the behaviour of your reproductive hormones throughout your cycle, giving you and your doctor a clearer hormonal picture to work from and guidance on how to best manage this transitional phase.
What’s the difference between perimenopause and menopause?
Perimenopause and menopause are different stages of the menopause.
- Perimenopause – a natural transitional phase that leads up to menopause, periods are likely to become less regular and you can experience a range of symptoms. During this phase, oestrogen levels will steadily decline.
- Menopause – this phase is denoted by the end of ovulation, usually defined by more than 12 months since the last period. Oestrogen levels will remain at their lowest levels. The majority of “menopause symptoms” actually refer to those experienced in perimenopause.
When can I start HRT during perimenopause?
It is recommended that you start HRT as soon as you experience symptoms related to perimenopause. Studies have shown that starting HRT earlier in the transition to menopause can reduce the risk of long-term conditions such as: osteoporosis, coronary heart disease, and cardiovascular disease.
You can learn more in the HRT guide on our blog.
How soon will the test arrive?
If you order your test before midday on a Monday to Friday then your kit will be dispatched the same day.
All our kits are sent out via Royal Mail Tracked24, so it should be with you within 1-2 working days.

Can I have someone take my blood for me?
Yes. We offer two options if you do not want to do our finger prick test. The first is a home appointment where a nurse comes to your home to take a blood sample. The second is to visit a Phlebotomy clinic near you that offers a blood sample service.
A blood sample will be taken from your vein and we will provide you with everything you need to give to the nurse to allow them to take the sample.
The nurse will give you the blood sample to return to us using the pre-paid envelope provided.
