What Your Period Says About Your Hormones: A Gynaecologist’s Guide

Growing up, a lot of women are taught to see their periods as nothing but a bother. All they are told is that their periods are something they’ll need to manage and move on from every month. But medically speaking, the menstrual cycle is the clearest indicator of our hormone health. Well ahead of any tests and scans, it is our periods that tell us if our hormones are in complete harmony. So, keeping that in mind, let us take a look at the indicators our menstrual cycle provides us and figure out when you may need a professional opinion.

What do the different phases of your period mean?

Every month, our body goes through four stages that together form one menstrual cycle. Each of these stages is dependent on our hormone levels and how they change over time.

The first stage is menstruation itself, when the oestrogen and progesterone hormones fall, and the lining of the uterus breaks down – as that happens, you’ll experience a bit of bleeding. Not to mention, the change in our hormone levels is actually why many feel more tired or low in energy during these days. The second stage is the follicular phase, in which our oestrogen levels rise again. This hormone is responsible for rebuilding the lining of your uterus and preparing the body for ovulation.

Ovulation, while the shortest of the four stages, is actually the most important of the bunch in terms of our fertility and overall cycle. It is the point at which an egg is released from the ovary, and our hormones reach their peak for a brief moment, particularly oestrogen and luteinising hormone.

Finally, you enter the last stage of your hormone cycle, the luteal phase, when progesterone takes charge of your reproductive system. This hormone prepares your uterus just in case an embryo implants, but if there’s no pregnancy, its levels naturally fall back down. As its levels finally dip, our body gets the signal that it’s time to shed the uterine lining once more, thereby completing the cycle. With this change in progesterone also comes all the symptoms that people tend to associate with their period: cramps, PMS, bloating, mood changes, and breast tenderness.

Are hormonal fluctuations during periods normal?

Yes, hormonal fluctuations during a menstrual cycle are completely normal. In fact, these fluctuations are quite important for our menstrual health – a flat hormonal profile would mean that something is amiss with your periods.

Of course, there is a difference to be noted between normal variation and actual hormonal imbalance here. It’s okay if you feel worn out during your period or more emotional in the days leading up to it. What’s not okay is pain that is so severe you cannot function, mood changes that feel out of control, or cycles that move from one rotation to the next somewhat unpredictably. If this is happening, then you must not ignore it and get yourself checked by a good gynaecologist in London as soon as you can.

What do different flow types in a period indicate?

Period flow varies widely from person to person. So, for one individual, what’s important is that they stay consistent and have a pattern that you can easily track. A very light flow often means that either your oestrogen levels are low or your uterus’s lining is somewhat thin. Conversely, heavier flow is linked not only to higher oestrogen levels but also to conditions such as fibroids.

If you get clots with the flow, there’s nothing to worry about, especially if it’s on a heavier day. But consistently large clots being passed or soaking through multiple pads or tampons every hour is a massive cause for concern.

What do different intensities of period pain mean?

Now, a bit of cramps during periods lie within expectations, since the uterus is shedding its lining when you feel them. If you’re feeling discomfort that ranges only from mild to moderate and can be easily managed with rest, home remedies, or a simple pain relief, there’s nothing to worry about.

But as mentioned before, experiencing pain so severe that it leaves you unable to work, exercise, or just go about your daily life, is not okay. A lot of people don’t realise it, but that level of pain may just be a symptom of conditions like endometriosis or adenomyosis. So if you’re experiencing severe pain right now, the first few things you need to do are to not normalise it, not chalk it up as just a part of the process, and get help as soon as possible.

What does your cycle length say about your hormones?

A lot of people often believe that our menstrual cycle refreshes every 28 days, and that applies to pretty much every woman out there. The truth is, a healthy cycle can range anywhere from 21 to 35 days, and what matters more is consistency. If your cycle lasts around 30 days without fail, with only 1-2 days’ variation, that’s a sign of regular ovulation and good hormonal balance. But if that isn’t the case – if your cycle varies widely in length and worse, swings from very short to very long – this could be a sign of ovulation problems and hormonal disruption. Stress, thyroid changes, and weight changes can all contribute greatly to this problem.

Why do irregular or missing periods happen?

Irregular periods are actually the most common reason why a lot of people seek a gynaecologist, being the clearest sign that something is well and truly off with our system. This irregularity can occur for many reasons, from stress to long-term hormonal conditions. Missing ovulation, even occasionally, is actually enough to throw the cycle off in its entirety. Should this continue for more than a few months, please understand that it will not resolve on its own, and there’s likely an underlying cause that needs work.

Missing periods are no different. Pregnancy is only one obvious cause, but it’s far from the only one. You can miss one cycle due to stress or illness. But repeatedly missing periods can happen from hormonal contraception, excessive exercise, eating disorders, thyroid imbalance, and early ovarian insufficiency.

What does your period colour say about your health?

The colour of our period blood often changes throughout our menstrual cycle. On heavier days, you’ll notice bright red blood, while dark brown blood is just older blood leaving the uterus more slowly. Anything other than that, particularly anything accompanied by a strong smell or a sudden discharge, is a clear indicator of an infection that needs to be assessed.

Generally speaking, black or brown period shade is just old and oxidised period blood cleaning itself out. Dark red or maroon blood indicates a healthy flow. Very dark or purplish flow is just a sign of heavy flow or blood mixed with many clots.

Pink flow can mean a few things, maybe even at once – blood mixed with cervical fluid, lower level of oestrogen, or blood deficiency. In a similar vein, you get an orangish flow when your blood mixes with vaginal discharge or cervical mucus. If it is accompanied by irritation or odour, that’s a sign of an infection.

Green or greyish discharge, not flow, can be a sign of an infection such as bacterial vaginosis or trichomoniasis, especially if it’s accompanied by a strong smell, itching, or discomfort.

When should you see a gynaecologist for period problems?

If you’re experiencing heavy bleeding, severe pain, missing or irregular cycles, and even one of them is impacting your quality of life, please avoid dealing with these problems on your own and book an appointment with a good gynaecologist. Seeing one can help you get all the answers you need, and you’ll be able to come up with a plan to treat any of these things with ease and comfort. That alone is way better than staying perpetually trapped in a harmful cycle.

Take care of your menstrual health

It is important to remember that, for women, menstrual health is closely tied to our overall health. Our nutrition, sleep, stress levels, and physical activity all affect how smoothly our hormones function. A change in your cycle, no matter how insignificant, deserves to be treated with seriousness and care. So just listen to your body when it tells you something. When you treat your menstrual cycle well and look after yourself, you go a long way toward living a better and healthier life.
