At Menstrual Matters, we are committed to providing clear, accurate and up to date information.

In collaboration with several expert clinicians, health associations, and leading research organisations, we work hard to ensure that our products and information are evidence-based, in line with relevant professional guidelines, and meet with the NHS Information Standard.- We hope to become a certified member of the Information Standard.

If you have any questions, or comments about any of the information that we are sharing, please do not hesitate to get in touch, through the ‘contact’ page.

There is currently very little large-scale menstrual cycle health data available for academic and clinical research purposes. So, the anonymous data created by users of the Menstrual Matters ‘Symptom Checker’ tool will provide much-needed information about the prevalence of cycle-related symptoms.

We will publish the results of any academic, clinical or internal research based on it, in the form of reports, articles, and website content. We will NEVER sell this data to any third party company, or other profit-making enterprise. It is for health research purposes, only.

If you use the Menstrual Matters symptom checker app, your profile data (e.g. name, email address) is only used to send you a one-off personalised report, and is only added to our mailing list if you indicate that you wish to receive newsletters.

Your health data, created by you as you fill in the symptom checker form, is immediately separated from your profile data (i.e. made anonymous)- then stored on a separate secure server, located in the UK.

Note- Please see our ‘privacy policy’ for full details.

Good question! In short, a combination of social, economic, and political factors have resulted in a gap in clinical/ public knowledge. These factors include:

• The menstruation taboo (which effectively silences open discussion about the menstrual cycle, as well as menstruation itself)
• Gender norms that position the female body as 'for' having babies and so menstruation (as an abortive function) is omitted from our education
• Pressurised medical consultations (time and money) that force a ‘most likely’ diagnosis, rather than one that takes account of all symptoms, and when they occur over the course of a menstrual cycle
• The dominance of the pharmaceutical industry in dictating which treatment options are clinically tested, favouring medication (which will make them profit) over dietary, or other non-medication approaches (which cannot be patented, and so are not profitable)
• Economic constraints that prevent governments and non-profit research organisations from funding much-needed clinical trials

The good news is that smartphone, and web application technology is now providing a means to collect menstrual health data easily and cheaply- and so we hope that we will soon be able to provide robust evidence to influence the way in which this topic is understood, by clinicians and the public.

Yes they might be... Some people are hospitalised by cyclical asthma attacks, epileptic seizures, or migraines. Although this is certainly not the case for the vast majority of people with a menstrual cycle, it is still possible, and worth checking, if only to discount it from the list of possible contributing factors/ triggers.

So, if you find that you feel much worse at certain times in your cycle, it is definitely worth tracking your symptoms over time, and if a pattern emerges, you can take steps to better manage your  health, as well as help your doctor make a more informed diagnosis.

No! There is a difference between normal '(pre)menstrual changes' and 'symptoms'. It is entirely possible to significantly reduce the severity of most normal cyclic changes, through anti-inflammatory diet and lifestyle changes alone.

In some cases, it can also be necessary to use medications, too, especially if an underlying health issue also needs to be addressed.

In contrast, regularly severe cyclic symptoms that prevent us from completing typical daily tasks, such as work or school- usually indicate an underlying health condition.

For too long we have accepted and coped with severe cyclic pain, or emotional distress, in silence. We are taught to expect these things, and to get on with our lives despite them, or risk negative consequences. We are made to feel that these problems are ‘not real’, or ‘in our heads’. It is not normal to be debilitated by your menstrual cycle.

Actually, many people have suddenly developed side-effect symptoms after taking the same medication for a long time, without any previous problems. Multiple factors can influence the way in which you react to synthetic hormonal medications- age, diet, exercise levels, other health issues, weight loss/gain, stress, sleep patterns, pregnancy, miscarriage, menopause, or surgery.

So, it is important that you and your doctor keep an open mind about the potential role of hormonal medication(s) in your symptoms of ill health; always check symptoms against those listed on the medication information sheet.

The term '(pre)menstrual' actually refers to inflammatory changes ocurring the time from ovulation to the end of menstruation.

Many people experience symptoms around ovulation, as well as just before and during menstruation, perhaps with a gap between these times. This can mean that you feel like your symptoms are 'on/off' all the time, but tracking will usually reveal a pattern.

Track those symptoms! If you have a menstrual cycle, tracking your symptoms over three months will reveal any patterns in their occurrence. This will help you to confirm any cyclical issues, and allow a doctor to consider this useful information, too.

It is then worth reading our ‘symptom management’ section to see if you are able to improve your health and well-being through dietary, or lifestyle, changes. It is best to try these approaches for at least three months, since this is how long it can take for physiological changes to occur- although many people notice a difference within a month.

If you do not have a menstrual cycle, but are taking hormonal medication, or have a dietary or other physiological issue, that could affect your health, it can still be useful to track your symptoms. This can help identify any external triggers e.g. food allergies, activities, or medications, as well as help you to monitor any improvements in health and well-being once ‘managing’ your symptoms.

Yes. It is still possible to experience symptoms of underlying health conditions while taking contraceptive medication. Especially if you find your symptoms worsening just before menstruation when you are on a 'pill gap'.

Research suggests that some conditions are triggered or worsened by the normal physiological changes involved in the menstrual cycle (i.e. those involving systemic inflammation, or blood loss). So, if you forget to take a pill at the usual time, or take a 7 day gap each month to trigger a 'withdrawal bleed', your body may start to experience some of these changes, which could result in symptoms.

It is also a good idea to track symptoms when changing type of hormonal medication/device, to see if the new option has any effect on your health. Be aware that it can take up to 3 months for your body to adjust to hormonal medications, so don't be too quick to stop tracking- this information can be very useful when discussing your experiences with your doctor.

So long as your doctor has asked you to track your symptoms over time (if you have a menstrual cycle), or double checked that your symptoms are not listed as side-effects to your hormonal medication, this is absolutely fine! Your doctor might be aware of the possibility of these contributing factors but has decided that they are not a contributing factor in your ill health.

But, if not, then it is certainly worth tracking your symptoms over time to identify for yourself, as well as your doctor, any patterns in their occurrence. If your symptoms happen in any sort of regular way, or at similar phases of your cycle, then your doctor should see that there could be a link.

Likewise, if you feel sure that you have only developed your symptoms whilst taking a particular hormonal medication, then your doctor ought to be open to trying alternative options in your treatment.  Remember- the sex hormones are not pathological- different hormonal medications have different effects on individuals- please try multiple types- rather than dismissing all hormonal medication options straight away. You can always ask for another doctor's opinion if you feel that you are not being listened to.

It is important that you wait at least three months before judging any change in diet, lifestyle, or medication. It can take this long for your body to adapt to changes, although most people do notice a positive difference within a month.

All of the symptom management changes that are recommended, promote a healthy diet and lifestyle, so there is very little chance of these changes having a negative impact on your health and well-being. So, your next step is to follow up with your doctor, to make sure that there is definitely no underlying health issue. Share your symptom checker and tracker information with your doctor to help them make an informed diagnosis.

If you are still left without a diagnosis, you could perhaps try consulting a dietitian who specialises in cyclical issues... It could be that you are lacking a key mineral in your diet, or would benefit from some sort of nutritional advice.

Many health conditions are known to interact with the menstrual cycle e.g. anorexia, obesity, diabetes, PCOS (Polycystic Ovary Syndrome), endometriosis, epilepsy, narcolepsy, migraine, anxiety, Irritable Bowel Syndrome, fibromyalgia, chronic fatigue syndrome, asthma, depression, hyper/hypothyroidism, and many more…

Checking and tracking your symptoms, to identify a cyclical factor in your health condition is obviously still a good idea. You may be able to alleviate some of your symptoms through simple lifestyle changes. Although, in some cases, e.g. endometriosis, the only way to entirely prevent symptoms may be through the use of hormonal medication, or a device like the Mirena IUS. It is very important to try and stop periods/ cyclic bleeding in the body.

All of our recommended symptom management tips and tricks promote a healthy diet and lifestyle, so there is usually no problem with trying these approaches whilst also being treated for another health issue. However, it is best to consult your doctor, or dietitian, before significantly changing your diet e.g. becoming vegetarian, or reducing your consumption of dairy products, in case this reduces your intake of critical nutrients required to improve your health condition. Don't worry- there are plenty of supplements available!

Menopause can cause, or affect, many of the same symptoms and health conditions associated with the menstrual cycle. Typically, menopausal symptoms will arise from decreasing levels of oestrogen, but can also be down to insufficient dietary intake of critical minerals or nutrients.

We do encourage menopausal people to use our tools and information, since they basically promote a healthy diet and lifestyle, which will usually help to alleviate menopausal symptoms, too. The only reason why we do not have a specific focus on the menopause, is that our research niche is in documenting and researching the relationship between the menstrual cycle and ill health.

But, please do share your experiences of, and ways of managing, symptoms caused by the menopause. We will certainly share research findings and useful products and resources for those going through the menopause. We might even be able to move into menopause-specific research one day...

Let us know your experiences through our contact page.

If you have access to a family planning clinic, make an appointment to speak to someone there- they are best placed to discuss your contraceptive options. If not, your General Practitioner doctor (GP) should also know about this subject, although some are not able to provide the full range of contraceptive options available through an NHS (free) prescription, due to budget restrictions.

There are various contraceptive options available, but each method has a different ‘failure rate’- so it is important that you choose a method that best fits your circumstances and health.

For those of you interested in learning more about manging your fertility (either to prevent pregnancy, or try to get pregnant) without the need for hormonal medication, or devices, the Family Planning Association has some useful info here: http://www.fpa.org.uk/contraception-help/natural-family-planning

No- Menstrual Matters is a non-profit organisation, and we want to offer independent and unbiased information to our audiences. Therefore, we do not accept funding from the pharmaceutical industry, disposable sanitary product companies, or any other source that could create a conflict of interest.

You will notice that the products listed in our ‘resources’ section are our own research-based items. We are not interested in making money for ourselves at the cost of our users’ health and well-being, or risking our impartial and independent research reputation.

We do tend to promote menstrual cups in general because they are the best menstrual management product available (they are environmentally responsible, long lasting, cheap, allow the user to monitor their hormonal health, build self-esteem, and take part in any activity of their choosing). We sometimes promote Mooncup, in particular, because it is a high quality medical-grade silicon product, and is translucent, which enables the accurate monitoring of blood loss at menstruation. Mooncup is also the most widely available and only ethically certified menstrual cup company in the UK.

Menstrual Matters does accept donations from individuals who wish to support our work. All money donated (100%) goes towards the work of Menstrual Matters, and we share our annual reports on the website to show how that money has been spent.

So far, Menstrual Matters has mainly been funded by our founder, and donations from friends and family.

Please get in touch if you have any questions about our funding, or legal status, through the ‘contact’ page.
