The period cycle: What happens in your body beyond the five days of bleeding | India News

“Chill! It’s just periods. You’ll feel better in a couple of days.”But do women really get better in three to five days or are they caught in a recurring loop of exhaustion, mood swings and hormonal shifts that returns month after month from their first period till end.From hormonal fluctuations and ovulation to fatigue, bloating and premenstrual symptoms, the menstrual cycle is a month-long process that extends far beyond the days of bleeding. Yet, what happens inside the body between periods remains poorly understood by many women.For some, menstruation brings severe cramps, exhaustion and an overwhelming need to be left alone. Others struggle with bloating, back pain, irritability or difficulty concentrating at work. And for many, the days leading up to a period can be just as challenging as the bleeding itself.“I feel like somebody is constantly stabbing me with a sword, not even a knife, in my stomach,” says Sasha Singh, describing her experience of menstruation.“Emotionally, I am so annoyed that eye rolls become the only friend that day. The Luteal phase is the worst for me, an indication of days ahead,” she adds.For Shivanghii, the physical discomfort comes with an emotional toll. “I feel like I need to punch whoever is talking to me and cry all the time. Physically its like my insides are getting drained and sawed repeatedly. I feel the first day and the day before that are the most painful.”Their experiences highlight how differently women can experience the menstrual cycle, both physically and emotionally. They also raise a larger question: What happens inside the body when there is no bleeding?The menstrual cycle is not confined to the three to seven days of menstrual bleeding. It is a continuous process involving hormonal fluctuations and changes in the ovaries and uterus, as the body prepares for a possible pregnancy.These changes can influence much more than the uterine lining. They may affect energy levels, sleep, appetite, skin, digestion and mood throughout the month.While some women notice distinct changes from one phase to another, others experience few symptoms beyond their period.

What is menstruation?

Menstruation is the shedding of the uterine lining through the vagina when pregnancy has not occurred. The bleeding contains blood and tissue from the lining of the uterus, also called the endometrium.Periods generally last between three and seven days, although the duration and amount of bleeding vary. Menstruation usually begins during puberty, most commonly between the ages of 11 and 14, though it can start earlier or later. It continues through the reproductive years until menopause, which typically occurs between the ages of 45 and 55.The menstrual cycle, however, covers the entire interval from the first day of one period to the first day of the next.A cycle is often described as lasting 28 days, but this is only an average. Many adults have cycles that fall within a range of approximately 21 to 35 days, and cycle length can vary with age and individual circumstances.The cycle is regulated by hormones that coordinate activity between the brain, the ovaries and the uterus. Its four commonly described phases are menstruation, the follicular phase, ovulation and the luteal phase.Importantly, these phases are not four completely separate stages. The follicular phase begins on the first day of menstruation and continues until ovulation, meaning the first two phases overlap.

The four phases: What happens inside the body?

MenstruationThe menstrual cycle begins on the first day of menstrual bleeding. When pregnancy has not occurred, the levels of hormones that support the uterine lining fall, prompting the lining to shed.The uterus contracts to help expel this tissue, which can cause cramps in the lower abdomen and sometimes pain in the lower back. Some women also experience bloating, headaches, fatigue, breast discomfort or changes in mood.For Priyanka, the first two days can be particularly difficult. “During my period, I usually feel physically tired, bloated and uncomfortable, with severe cramps and lower back pain. Emotionally, I tend to feel more irritable, sensitive and overwhelmed than usual. The most challenging phase for me is the few days leading up to my period the Luteal phase, when PMS symptoms like mood swings, fatigue and bloating are at their peak. The first two days of my period can also be difficult,” she added.Sneha, who works in the news field, says the physical discomfort can make demanding workdays more difficult.“The first three days are the most challenging for me. I, Sneha, usually feel drained due to severe stomach aches, which makes working in the news field even more physically and mentally exhausting.”Hormone levels, particularly those of oestrogen and progesterone, are relatively low at the beginning of the cycle. But this does not mean that the body’s reproductive processes have stopped. As menstruation begins, hormones are already signalling the ovaries to start developing follicles for the next stage.For most women, some discomfort during menstruation can be managed with appropriate measures. However, severe pain that interferes with daily activities should not automatically be dismissed as a normal part of having periods.The follicular phaseThis phase starts on the first day of menstruation and continues until ovulation.During this time, the pituitary gland releases follicle-stimulating hormone (FSH), which stimulates the development of follicles in the ovaries. Each follicle contains an immature egg, and usually one becomes dominant and continues to mature.As the follicle develops, it produces increasing amounts of oestrogen. This hormone helps rebuild and thicken the uterine lining after menstruation.The changes are taking place even after the bleeding stops, although they may not produce obvious symptoms.Some women report feeling more energetic or focused during the days after their period. Others do not notice any clear difference. These experiences can vary from one person to another and even from one cycle to the next.Vijaya notices significant changes in her energy and concentration around her cycle. “Oh yes!! It changes drastically. Energy drops, concentration is hindered. Sleep becomes overpowering, as if body is on energy saver mode.”However, it is important not to assume that every change in energy or mood is caused by menstrual hormones. Sleep, stress, nutrition, underlying health conditions and other factors can also influence how someone feels.The follicular phase illustrates why the menstrual cycle is more than a monthly episode of bleeding. While the body prepares an egg for possible release, the uterine lining is also being rebuilt.OvulationAs the dominant follicle matures, rising oestrogen levels help trigger a surge in luteinising hormone (LH). This surge causes ovulation, when the ovary releases a mature egg.Ovulation is often described as occurring around day 14 of a 28-day cycle, but its timing varies. It does not necessarily happen on the same day for everyone, or even in every cycle for the same person.After its release, the egg enters the fallopian tube, where it may be fertilised by sperm. The egg usually remains capable of fertilisation for approximately 12 to 24 hours. However, pregnancy can occur from sex in the days leading up to ovulation because sperm can survive in the reproductive tract for several days.Some women notice changes around ovulation. Cervical mucus may become clearer, wetter and more slippery, while some experience mild pain on one side of the lower abdomen. Others may notice no obvious physical changes.There is also considerable variation in whether women report changes in mood, energy or sexual desire around this time. These experiences should not be treated as universal signs of ovulation.Understanding ovulation is important not only for those trying to conceive but also for anyone seeking to understand the timing of their cycle. Calendar estimates and period-tracking apps can help identify patterns, but they cannot always predict the exact day of ovulation.

The luteal phaseAfter ovulation, the follicle that released the egg transforms into a structure called the corpus luteum. It produces progesterone, along with some oestrogen, to help maintain the uterine lining in preparation for a possible pregnancy.If pregnancy does not occur, the corpus luteum breaks down. Progesterone and oestrogen levels fall, triggering changes that eventually lead to the shedding of the uterine lining and the start of the next period.For some women, this phase brings premenstrual symptoms, commonly known as PMS. These may include bloating, breast tenderness, headaches, fatigue, irritability, changes in appetite and difficulty sleeping.Priyanka says the days before menstruation can be particularly challenging, with mood swings, fatigue and bloating. Natasha also describes the luteal phase as a warning of the discomfort to come.Shivanghii says the emotional changes can be difficult to explain. “Getting irritated all the time and crying for no reason. It feels like everyone is being rude to me and they all hate me. No particular change in sleep.”Sneha, meanwhile, says irritability is the main change she notices: “Mood: Yes, but not with other things. I get irritated easily during my period.”Premenstrual symptoms vary considerably. Some women experience mild changes that do not disrupt their routines, while others experience symptoms that affect work, relationships, studies and everyday activities.In more severe cases, symptoms may be associated with premenstrual dysphoric disorder (PMDD), a condition that can cause significant emotional and physical distress.Women experiencing severe or persistent symptoms should discuss them with a healthcare professional rather than assuming they must simply endure them.

Why do hormones affect mood, energy, sleep & appetite

The effects of the menstrual cycle can extend beyond reproductive organs. Changes in oestrogen and progesterone may influence several bodily functions, although the extent of these effects differs between individuals.According to Dr Asha Susawat, senior obstetrician and gynaecologist at Cocoon Hospital, Jaipur, hormonal fluctuations can influence how women feel throughout the cycle.“While the hormonal fluctuations will be much more impactful than just your bleeding pattern, their importance will vary from woman to woman. For some, high levels of oestrogen before ovulation make them feel more energetic. Others will not perceive any significant differences. Following the occurrence of ovulation, the progesterone hormone increases the temperature levels in the body and may affect the sleep pattern. As the woman starts to bleed, some may feel sleepy, irritable, nervous, food craving, among other symptoms such as breakout, bloating, constipation, or diarrhoea. Nevertheless, not all the factors are felt by everyone and need more diagnoses.”

Dr Rhythm Bhalla, senior consultant in obstetrics and gynaecology at Cocoon Hospital, Chandigarh, similarly notes that symptoms can begin before the next period arrives.“The physical effects of menstrual cycle on women may start long before the upcoming period. Variations in levels of oestrogen and progesterone affect moods, sleep, eating and energy levels. However, there is no standard experience in this regard since some women feel better before ovulation whereas some start experiencing fatigue, poor sleep, cravings and irritability prior to the onset of the period. Women may start experiencing acne and bloating, while digestive problems may turn into constipation or diarrhoea before the period starts. There may be minor symptoms but serious problems should not be overlooked.”

More than mood swings: The body’s changing rhythms

Some women experience irritability, anxiety, sadness or emotional sensitivity in the days before their period. Others notice little change, or find that their mood varies for reasons unrelated to their cycle.Priyanka says she becomes more irritable and anxious before menstruation and sometimes struggles to concentrate. Shivanghii describes feeling upset and easily irritated, while Vijaya reports a noticeable decline in concentration and energy.These accounts demonstrate the importance of recognising individual patterns. Hormonal fluctuations may contribute to mood changes, but they should not become a blanket explanation for every emotional response a woman experiences.Sasha’s experience highlights another problem with how menstruation is discussed. Her first lessons about periods came in school, but the experience left her with questions about how much girls were actually being taught.“I got my orientation to montly bleeding from school. It was a workshop conducted by Whisper for 7th class girls (boys were told it is a free PT period) when they poured blue ink on a sanitary pad in the name of ‘sexual education’,” she recalls.Years later, she encountered a different kind of misconception at work. “When I worked in an all-boys work desk, I was often asked if I was on periods if I was not in a cheerful mood. Bad mood can be a product of multiple things, not just periods.”Some women notice acne or changes in skin oiliness around their period. Others experience food cravings, bloating, constipation or diarrhoea.These symptoms may be associated with hormonal fluctuations, but their causes can be complex. Persistent acne, unexplained hair loss, increased facial hair or substantial changes in weight should not automatically be attributed to the menstrual cycle.Sneha lists several changes she has noticed, “face pimple,facial hair, bloating, hair fall”The same applies to digestive symptoms. Occasional bloating or changes in bowel habits may occur around menstruation, but persistent or severe abdominal pain, ongoing digestive problems or symptoms that disrupt daily life warrant medical attention.

Stress, thyroid disorders & PCOS: What else affects the cycle

The menstrual cycle is regulated by a complex interaction between the brain, the ovaries and the uterus. Several factors can interfere with this process, affecting ovulation, the timing of periods and the amount of bleeding.Dr Susawat explains that stress can affect the hormones involved in ovulation, potentially delaying periods or causing them to be missed. Thyroid disorders can influence cycle length and bleeding patterns, while PCOS may interfere with regular ovulation and lead to irregular or absent periods.Age is another factor. Cycles may be irregular during the years after menstruation first begins and may change again during perimenopause, the transition towards menopause. Hormonal contraception can also alter bleeding patterns, depending on the method used.Dr Bhalla said that the cycle depends on several systems working together. “Periods are the result of interaction between the brain, the ovaries and the uterus; there are many things that might interfere in this interaction. Stress, combined with big changes in weight or poor eating habits, may lead to ovulation delay,” Bhalla said.“Thyroid issues may cause changes in bleeding amount and frequency. In PCOS, ovulation may be less frequent and make periods irregular. The menstrual problems can occur during the period of adolescence before the beginning of menopause. As hormonal contraceptives have an impact on the level of reproductive hormones and uterine lining in some form, so the bleeding can be less, spotting or absence of periods can occur,” she added.This means that a change in the menstrual cycle does not necessarily indicate a serious health problem, but persistent changes should not be ignored.A healthcare professional may consider factors such as stress, medication, pregnancy, thyroid function and PCOS when assessing irregular periods.

The information gap: What women know about their cycles

Despite menstruation being a regular part of life for millions of women, understanding of the complete menstrual cycle remains uneven. Many learn about bleeding at school or at home but receive little information about ovulation, hormonal changes or the symptoms that may occur between periods.When asked whether they knew hormonal changes continue throughout the month, even when they are not bleeding, the responses reflected different levels of awareness.Vijaya said, “Yes. The whole cycle is in process and goes beyond just shedding blood. There is constant hormonal fluctuations which ultimately affects the energy and motivation throughout the lifetime.”Prisha Patnaik responded, “Yes, I think 4 phases?”Priyanka said, “Yes, I know that the changing cycle can affect my mood, energy, sleep, appetite and concentration, even when we’re not on our period.”Shivanghii said, “I have a broad idea, like the luteal, follicular phases and all. Not really informed about the details.”Their responses illustrate a distinction between knowing that the cycle involves hormonal changes and understanding how those changes occur across its different phases.For many, school provides only the basics. Some learn more from their mothers, friends or online resources, while others have to seek information independently.Vijaya said, “I didn’t learn about periods at home, it was only until I got them did I have the conversation. In school it was only what textbook had to offer, they didn’t even teach about pads etc.”Priyanka said, “I learnt the basics at school, but very little about hormonal changes and their impact on our bodies. One common misconception I’ve encountered is that periods are just about bleeding, when they actually affect our physical and emotional well-being throughout the month.”Sneha said, “I don’t have much to say about how periods were discussed at school. I got most of my information at home and from Google, which I explored out of curiosity.”Shivanghii said, “I had my mother take me to a gynecologist to give me the talk, like covering all the aspects. School never, unfortunately, even slightly brushed against the topic.”These experiences underline the need for menstrual-health education that goes beyond explaining what bleeding is.Girls and boys need age-appropriate information about the menstrual cycle, reproductive health, common symptoms and when medical care may be necessary.

Menstruation, stigma and restrictions

In many parts of India, menstruation remains a subject surrounded by stigma and silence. Some women continue to face restrictions on entering kitchens, touching utensils, participating in religious activities or discussing periods openly.Pari (name changed), from Assam, describes the restrictions followed in her household.“On the three days of my period, I sit and sleep on the floor. I eat on a separate plate as I am not allowed to enter the kitchen or touch any utensil or other furniture. I do not touch any male member be it my father, brother or husband. These customs have been followed for a very long time in my household and me, my mother and sister have applied the same in our lives.”Her account reflects how cultural practices can shape women’s experiences of menstruation beyond the physical symptoms themselves.Yash Sonkar points to the gaps in menstrual-health education, saying, “Menstruation isn’t even properly explained in our school curriculum… teachers skip the chapters at times.”For Trisha, the problem goes beyond inadequate education to the stigma surrounding menstruation. One of the most persistent misconceptions she has encountered, she says, is that periods make women “impure”.Shivanghii’s experience reflects how deeply such beliefs can become embedded in everyday life. “As for misconceptions, it’s hard to think of one that I might not have been forced on. Days on which I can cut my nails, touching the pickle, touching gods or even mentioning it in front of a male entity,” she says, recalling the restrictions associated with menstruation.These beliefs can persist through seemingly ordinary practices, from discouraging women from entering places of worship to treating menstruation as something that must be kept out of sight.Even the habit of wrapping sanitary napkins discreetly or avoiding conversations about periods can reinforce the idea that menstruation is something to hide rather than a normal biological process.

When should you consult a gynaecologist?

Although changes in mood, energy and physical comfort may occur throughout the menstrual cycle, not every symptom should be attributed to hormones.According to Dr Susawat, excessive bleeding between periods, bleeding after sexual intercourse, persistent pelvic pain or pain during intercourse should be evaluated. Unusual vaginal discharge accompanied by an odour, irritation or fever also warrants medical attention.She adds that women should seek an assessment if their menstrual pattern changes significantly or if they miss periods for three months. If pregnancy is possible, a missed period may be a reason to take a pregnancy test.Dr Bhalla similarly advises that frequent bleeding between cycles, bleeding after intercourse, persistent pelvic pain and unusual discharge accompanied by itching, a bad odour or fever should not be ignored.She says, “This can be explained through the normal process of a woman. Abnormal bleeding that occurs frequently in between cycles, or bleeding following sexual intercourse, or constant pain in the pelvis area or during sexual intercourse should be dealt with appropriately. Unusual vaginal discharge accompanied by signs such as itching, bad odor and fever should be attended to. Irregular periods which result in absence of menstruation for over three months should also be considered and an examination carried out. This should be done as early as possible if pregnancy is one of the probable causes. Severe pelvic pain in addition to bleeding, missing periods and fainting should be handled as a matter of urgency. Excessive vaginal bleeding accompanied by weakness, dizziness and difficulty breathing should also be handled urgently.”Other warning signs include bleeding that lasts longer than seven days, very heavy bleeding, severe or worsening menstrual pain and symptoms that interfere with work, studies or daily activities.Heavy bleeding can lead to iron deficiency anaemia, particularly when it occurs repeatedly. Severe menstrual pain may also be associated with conditions such as endometriosis or adenomyosis, while irregular cycles may warrant assessment for PCOS, thyroid disorders or other underlying causes.Severe pelvic pain accompanied by a missed period, bleeding or faintness requires urgent medical assessment, particularly when pregnancy is possible.The key is to recognise the difference between a symptom that occurs occasionally and one that is persistent, severe or unusual for the individual.The World Health Organisation (WHO) recognises menstrual health as more than a matter of managing bleeding. It includes access to accurate information, affordable menstrual products, safe sanitation facilities, appropriate healthcare and the ability to participate in everyday life without stigma.The WHO has also highlighted the limited availability of high-quality scientific research on menstruation. Better research and education can help improve care, support health policies and challenge myths surrounding the menstrual cycle.The organisation estimates that around 500 million people who menstruate worldwide lack access to the full range of menstrual-health materials, facilities and services. It has also cited emerging national data indicating that around 39% of schools provide menstrual-health education.These gaps matter because a lack of information can prevent women from recognising symptoms that require medical attention. It can also make it harder for them to discuss menstrual difficulties without embarrassment or fear of being dismissed.

Beyond the five days

For many women, menstruation is the most visible part of a process that continues throughout the month. While the uterus sheds its lining, the ovaries begin developing follicles. As oestrogen rises, the uterine lining rebuilds.Ovulation follows, and progesterone helps prepare the uterus for a possible pregnancy. If pregnancy does not occur, hormone levels fall and the cycle begins again.The physical and emotional effects of these changes are not identical for everyone. Some women experience significant discomfort before and during menstruation, while others notice little variation.Understanding the menstrual cycle means recognising that periods are not simply five days of bleeding. They are one stage in a continuous process shaped by hormones, health, age and individual circumstances.Better menstrual-health education can help women understand their bodies, challenge stigma and recognise when symptoms deserve medical attention.
