Period Facts: What Indian Women Should Know About Menstruation

• A normal cycle is 21 to 35 days long, with 3 to 7 days of bleeding and about 30 to 50 mL of blood loss. The famous 28-day cycle is just an average, not a rule.
• The cycle has four phases (menstrual, follicular, ovulation, luteal) driven by FSH, LH, oestradiol, and progesterone. Disruption at any level shows up as a specific cycle change.
• Heavy bleeding (soaking through protection hourly, large clots, periods over 7 days), severe pain that disrupts life, bleeding between periods or after sex, and any sudden new pattern all warrant evaluation.
• India offers many menstrual products: pads, tampons, cups, cloth pads, and period underwear, plus subsidised government pads from Re 1 per pad.
• Cultural restrictions during periods (no kitchen, no temple, no bathing) have no medical basis. Bathing, normal diet, and normal activity are all safe and recommended.

Understanding the basic biology makes everything else easier to interpret. The menstrual cycle is a hormonally driven monthly rhythm that prepares the body for a possible pregnancy and resets when pregnancy does not occur. It moves through four phases that flow continuously into each other.

Menstrual phase (roughly days 1 to 5). The bleeding phase. The lining of the uterus (the endometrium) that built up during the previous cycle is shed through the cervix and out through the vagina. Bleeding typically lasts 3 to 7 days. Day 1 of the cycle is the first day of full menstrual flow.

Follicular phase (roughly days 1 to 13, overlapping with the menstrual phase). The pituitary gland releases follicle-stimulating hormone (FSH), which prompts a group of small follicles in the ovary to grow. One dominant follicle is selected by around day 7 and produces oestradiol, which rises steeply. The endometrium rebuilds, thickening from 1 to 2 mm up to 8 to 12 mm by ovulation, and cervical mucus turns clear, stretchy, and slippery. See our explainer on the follicular phase for more detail.

Ovulation (around day 14). Peak oestradiol triggers a surge of luteinizing hormone (LH) from the pituitary, which causes the dominant follicle to rupture and release the egg into the fallopian tube. The egg survives 12 to 24 hours. About 20 to 30 per cent of women feel mild one-sided pelvic pain at ovulation, called mittelschmerz. Learn how the LH surge drives ovulation and what ovulation actually means for fertility.

Luteal phase (roughly days 15 to 28). The ruptured follicle becomes the corpus luteum, which produces progesterone. Progesterone prepares the endometrium for possible implantation. If no pregnancy occurs, the corpus luteum regresses around day 24 to 26, progesterone and oestradiol drop, and that hormonal drop triggers the next period. PMS symptoms peak in the late luteal phase.

The hormonal cascade. Hormones from the hypothalamus (GnRH) and pituitary (FSH and LH) drive the cycle, while ovarian hormones (oestradiol and progesterone) respond and feed back. This interplay produces the predictable monthly rhythm. Disruption at any level (stress, pituitary dysfunction, ovarian conditions like PCOS, or premature ovarian insufficiency) produces specific cycle abnormalities.

What varies between women. Cycle length (21 to 35 days is typical; 28 is popular but not universal), bleeding duration (3 to 7 days), total blood loss (10 to 80 mL, averaging 30 to 50 mL), and symptom severity all differ. Each woman's pattern is her own. Comparing with friends is useful for context, but your cycle is individual.

What changes across life. Menarche (the first period) usually arrives between age 11 and 15 in Indian girls, and cycles are often irregular for the first year or two as the hormonal axis matures. The 20s and 30s are usually the most regular years. In the late 30s and 40s, cycles may shorten as ovarian reserve declines, then become increasingly irregular through perimenopause. Menopause (around age 46 to 50 in Indian women) is confirmed after 12 consecutive months without periods. Periods are also absent in pregnancy and may be irregular during exclusive breastfeeding, and hormonal contraception can modify or stop them.

What period blood actually contains. It is a mix of blood, endometrial tissue, cervical mucus, and vaginal secretions. Volume is heavier on days 1 to 2 and lighter afterwards. Colour ranges from bright red (fresh) to dark red or brown (older blood) to pink (light flow mixed with mucus). Small clots are normal on heavy days; clots larger than a 50-paise coin warrant a check.

The Indian menstrual product market has expanded a lot over the past decade. Each option has its own characteristics, costs, and best uses, and many women combine more than one. For a fuller comparison, see period products 101: pads, cups, and tampons.

Disposable pads. Still the most common product in India. Brands include Whisper, Stayfree, Sofy, Niine, and the government-distributed Suvidha, at roughly Rs 30 to 150 per pack. Widely available at kirana stores, pharmacies, and online. Easy to use with no learning curve, but single-use, so disposal matters. Cost per cycle is around Rs 80 to 300.

Tampons. Internal absorbent products, less common in India but growing among urban women. Brands include Tampax and Sofy, at about Rs 150 to 400 per box. They are invisible, allow swimming, and suit active days, but need changing every 4 to 8 hours and carry a small risk of toxic shock syndrome with prolonged high-absorbency use; see tampon and cup safety.

Menstrual cups. Reusable silicone cups that collect rather than absorb flow. Indian brands include Sirona, Pee Safe, Stonesoup, and Boondh, at roughly Rs 300 to 1,500, lasting 5 to 10 years. They are economical over time, eco-friendly, can be worn up to 12 hours, and carry a lower TSS risk than tampons. There is a real learning curve for insertion and removal; our guide on how to use a menstrual cup walks through it.

Reusable cloth pads. Washable cotton pads from brands such as Saukhyam and Eco Femme, at about Rs 100 to 500 each, lasting 1 to 3 years. Economical and eco-friendly, but they need proper washing and drying.

Period underwear. Underwear with built-in absorbent layers, from brands such as Adira, Lavos, and Sirona, at roughly Rs 500 to 2,500 per pair. Convenient and good for overnight, but the upfront cost is higher and you need several pairs.

Government-distributed products. Suvidha pads are sold at Re 1 per pad through 8,000-plus Jan Aushadhi Kendras under the Janaushadhi Suvidha scheme. Free pads are also distributed through schools and ASHAs in many state programmes. Sanitary pads were exempted from GST in July 2018, which improved affordability.

How often to change. Pads every 4 to 6 hours by day and 6 to 8 hours overnight; tampons every 4 to 8 hours and never beyond 8; cups every 8 to 12 hours. Dispose of pads and tampons wrapped in paper or a disposal bag in the bin, never flushed.

Period pain (dysmenorrhoea) and premenstrual symptoms affect most menstruating women to some degree. Management ranges from simple self-care to medical treatment.

Primary vs secondary dysmenorrhoea. Primary period pain has no underlying condition and is caused by prostaglandin-driven uterine contractions during shedding. It usually starts with the flow, peaks in the first 24 to 48 hours, and often improves with age. Secondary dysmenorrhoea is linked to a condition such as endometriosis, adenomyosis, or fibroids, and tends to develop later in life, worsen over time, come with other symptoms, and respond poorly to first-line treatment. For more, see period pain relief and our painful periods guide.

NSAIDs. Non-steroidal anti-inflammatory drugs are the first-line medicine because they block the prostaglandins that cause cramping. Common options in India include ibuprofen 400 to 800 mg three times daily, mefenamic acid 500 mg three times daily, naproxen 500 mg twice daily, and diclofenac 50 to 75 mg twice daily, taken for the first 2 to 3 days of the period (Brufen, Meftal, Naprosyn, and similar, at roughly Rs 30 to 200 per pack). Starting at the first sign of the period, or even the day before for predictable cycles, works better than waiting for the pain to peak. Take with food, and avoid NSAIDs in pregnancy, with kidney disease, or if you have an NSAID allergy.

Heat. A hot water bottle, electric heating pad, stick-on heat patch, or a warm bath relaxes the uterine muscle and eases cramping; it can be as effective as NSAIDs for mild to moderate pain and is safe (yes, you can bathe on your period).

Movement and lifestyle. Gentle exercise such as walking, swimming, stretching, or cycle-friendly yoga releases endorphins and improves circulation. Reducing caffeine and salt, getting enough omega-3, magnesium, calcium, and vitamin D, sleeping well, and managing stress all help. Because periods cause blood loss, maintaining good iron intake matters; heavy bleeding is a common cause of iron deficiency in women.

Hormonal contraception. Combined pills, the hormonal IUS, the implant, and DMPA reduce or stop menstrual pain in many users and are a reasonable option if you also need contraception. See everything you need to know about the pill.

Traditional approaches. Many Indian women use ginger tea, ajwain water, methi, or Ayurvedic formulations alongside conventional care. The evidence varies, but most are low-risk and may help some women.

PMS and PMDD. Mild to moderate PMS responds to lifestyle measures, reduced caffeine and salt in the late luteal phase, and calcium or magnesium. Moderate to severe PMS may benefit from combined hormonal contraception or SSRIs, and PMDD has strong evidence for SSRI treatment (such as sertraline or escitalopram), warranting a psychiatric or gynaecological consultation.

Several common conditions in Indian women present mainly through changes in the menstrual pattern. Recognising the pattern helps you seek timely evaluation.

Polycystic ovary syndrome (PCOS). Affects roughly 9 to 22 per cent of Indian women of reproductive age. It features irregular periods from infrequent ovulation, signs of excess androgens (extra facial or body hair, acne), and polycystic ovaries on ultrasound, often with insulin resistance. Diagnosis uses the Rotterdam criteria (2 of 3 features, with other causes excluded). Management combines lifestyle change, hormonal treatment, and fertility support when relevant; see PCOS treatment options.

Endometriosis. Affects about 10 per cent of women of reproductive age and is under-diagnosed in India. Endometrial-like tissue grows outside the uterus, causing inflammation and pain. It presents with severe period pain that worsens over time, chronic pelvic pain, pain with intercourse or bowel movements, and sometimes infertility. Read what endometriosis is for the full picture.

Uterine fibroids. Very common, with up to 70 to 80 per cent of women having them by age 50. Most are small and silent, but symptomatic fibroids cause heavy bleeding, pelvic pressure, and sometimes fertility issues. Management ranges from watchful waiting to medication to surgery; see uterine fibroids.

Adenomyosis. Endometrial tissue grows into the muscular wall of the uterus, causing painful, heavy periods and an enlarged, tender uterus. See adenomyosis treatment and management.

Thyroid and prolactin disorders. Both hypothyroidism and hyperthyroidism disturb cycles; hypothyroidism is common in India, so a TSH test is part of evaluating menstrual irregularity (see hypothyroidism in women). Raised prolactin suppresses ovulation and causes irregular or absent periods and sometimes milky discharge; see high prolactin.

Premature ovarian insufficiency. Loss of ovarian function before age 40, with irregular or absent periods and oestrogen-deficiency symptoms; see primary ovarian insufficiency.

Bleeding disorders and endometrial pathology. Inherited bleeding disorders can cause heavy periods from menarche onwards and are often missed in women. Polyps, hyperplasia, and (uncommonly, but increasingly relevant with rising obesity and PCOS) endometrial cancer can cause abnormal bleeding; persistent abnormal or postmenopausal bleeding should be checked, as covered in endometrial cancer warning signs.

Menstruation in India is layered with cultural, religious, and ritual practices that vary widely across regions, communities, religions, and families. There is no single Indian practice; experiences are shaped by family and individual circumstances, and generalisations are only starting points.

Common restrictions in some communities. These can include staying out of the kitchen, not entering temples or prayer rooms, not touching religious objects, separate sleeping arrangements, restrictions on hair-washing or bathing, dietary rules, and limits on travel or social activity. The Sabarimala temple case, challenged in the Supreme Court in 2018, brought some of these practices into national conversation.

The medical view. None of these restrictions have a medical basis. Menstruating women are physiologically the same as non-menstruating women in every relevant way; they can safely prepare and eat food, bathe, and carry on normal activity. FOGSI, ICMR, and the Ministry of Health and Family Welfare are all clear that menstrual hygiene includes regular bathing, a normal diet, and normal activity.

The impact. Restrictions can cause shame about a normal bodily function, missed school (a documented issue in Indian education research), and internalised stigma. Films like Padman (2018) and the documentary Period. End of Sentence. (2019), along with social media, have opened up the conversation, and younger women increasingly choose for themselves how to engage with family traditions. Within any cultural context, that choice is personal. The medical evidence supports normal activity during menstruation; the cultural choice is separate.

India has built substantial public health infrastructure for menstrual hygiene over the past two decades, though gaps in access, education, and cultural acceptance remain.

• Menstrual Hygiene Scheme (2011): Promotes menstrual hygiene among rural adolescent girls aged 10 to 19, providing subsidised pads through ASHAs (around Re 1 per pad) plus education and disposal awareness.
• Janaushadhi Suvidha (2018): Distributes Suvidha pads at Re 1 per pad through 8,000-plus Jan Aushadhi Kendras.
• GST removal (2018): The 12 per cent GST on sanitary pads was removed after sustained advocacy, improving affordability.
• School and adolescent programmes: The Rashtriya Kishor Swasthya Karyakram and various state schemes include menstrual hygiene education and product distribution.
• WASH integration: Menstrual hygiene is built into the Swachh Bharat Mission, including girl-friendly school toilets with disposal facilities.
• NGO and private contributions: Organisations such as Goonj, Eco Femme, Saukhyam, Plan India, and the Menstrual Health Alliance India work on access and education.

Beyond product choice, a few simple practices keep periods comfortable and healthy.

• Vulvar care: Gentle cleaning with plain warm water is the safest universal approach. If you use a wash, choose a pH-balanced intimate wash (V-Wash, Sirona, and similar). Avoid scented soaps, sprays, and douching, and always wipe front to back.
• No douching: The vagina is self-cleaning. Internal washing disrupts healthy flora and raises the risk of bacterial vaginosis and infection. External (vulvar) washing is enough.
• Underwear: Breathable cotton is best during periods. Change daily, and more often if soiled.
• Odour: Period blood develops an odour over hours; regular changes and daily bathing manage it. A strong, fishy, or foul smell can signal bacterial vaginosis and should be checked.
• Cleaning reusables: Rinse a cup between empties and sterilise it by boiling for 5 to 10 minutes between cycles. Rinse cloth pads in cold water first, wash with mild detergent, and dry fully.
• Swimming and exercise: Both are safe with a tampon or cup, and light to moderate exercise often eases cramps and lifts mood. Listen to your body about when to rest.
• Sleep and intimacy: Higher-absorbency overnight protection or a cup helps on heavy nights. Sex during a period is medically safe; remove a tampon or cup first (a menstrual disc is the only product that can stay in), and use a condom for STI protection regardless of cycle timing.

Tracking your cycle is one of the most useful things you can do for self-knowledge and for clear conversations with a doctor, and it can be as simple or detailed as you like.

Basic tracking means noting the first day and length of each period. Over 3 to 6 months this reveals your cycle length, regularity, and duration. Detailed tracking adds flow, pain, mood, cervical mucus, intercourse timing, medications, and lifestyle factors for a richer picture. You can use a paper calendar, a notes app, a dedicated period app (Flo, Clue, and Indian options with regional language support), or a wearable. Even minimal tracking is valuable, and a no-app approach works fine too; see tracking your cycle without an app.

What tracking reveals: your personal pattern, predictable symptoms, early signs of abnormalities, the link between cycle and stress or sleep, and your fertile window. What it does not do is diagnose conditions; app predictions are estimates, especially with irregular cycles, and should sit alongside professional advice.

A note on privacy: period apps collect intimate data, so read the privacy policy and consider what is shared with third parties. Some women prefer apps that store data locally, or plain calendar tracking. Whatever you choose, bringing your records to a gynaecology appointment makes the visit far more accurate than relying on memory, and many find that tracking without shame is a genuinely empowering part of menstrual health.
