A woman's health is intricately linked to her menstrual cycle, which is an important sign of her overall well-being. Throughout puberty and menopause, hormonal changes affect not only fertility but also mood, energy, and long-term health. A normal cycle usually indicates balance, whereas abnormalities may suggest problems such as PCOS, endometriosis, or thyroid disease.

Our bodies do not always work in a perfect clockwork operation and unexpected vaginal bleeding can often confused us. Is it a mere spotting? A normal period? A symptom of something more concerning? Differences between spotting, menstrual bleeding, and intermenstrual bleeding should be understood is crucial for maintaining reproduction health.

Here is a short guide to help you differentiate while you are confused.

Spotting

Spotting is vaginal bleeding that doesn't happen as part of your regular menstrual period. It commonly manifests as fine droplets or smears of blood on clothing or toilet tissue. The intensity of the blood ranges from deep red (recent blood) to pink (having cervical mucus mixed in it) or brown (older, oxidized blood). Spotting is not very much and can't be seen in a way that needs either a tampon or a pad to absorb.

Common Causes of Spotting

Spotting is caused by numerous factors, and in the majority of instances, it is nothing to worry about. Some frequent causes are:

Hormonal Birth Control Transitions: New birth control technique, for instance, birth control pills, IUDs containing hormones, or implants, results in temporary spotting as the body adapts.

Ovulation Bleeding: A few individuals get spotting light around the time of ovulation as a result of hormonal changes. It normally happens in the mid-cycle and could be followed by slight cramping.

Cervical Ectropion: A harmless condition when cells from the inside of the cervical canal migrate to the outer cervix, causing the outer cervix to become more sensitive and prone to faint bleeding on coitus or physical activity.

Early Pregnancy (Implantation Bleeding): 15–25% of pregnant women experience light spotting around 10–14 days post-conception, which is confused with an early period.

When to See a Doctor

Spotting is usually harmless, but it's best to consult a doctor if:

• It continues after a few months of initiating new birth control
• Is accompanied by pelvic pain or abnormal discharge
• Occurs after frequent intercourse
• Occurs during pregnancy and is not verified as implantation bleeding

Menstrual Bleeding

There is a time, also known as a period or menstruation, when the uterine lining sheds due to changing hormone levels. It would last for approximately 2-7 days and is heavier initially. The hue and texture of period blood shift during the menstrual cycle:

Red: New active bleeding at the start of a period

Brown or dark red: Older, slower blood in leaving the uterus

Clots: It's normal to have small clots, but bigger clots may be a sign of heavy menstrual bleeding (HMB)

Why You Have a Period Essentially?

Menstruation is a part of the reproductive cycle, and it happens around every 21–35 days. When there's no pregnancy after ovulation, hormone levels fall, causing the uterine lining to be shed.

Signs Your Period May Be Abnormal

Though periods differ in different people, there are some signs that point towards probable underlying conditions:

• Prolonged bleeding (longer than 7 days)
• Heavy flow necessitating pad/tampon changes every 1–2 hours
• Severe cramps that disrupt daily life
• Irregular periods or absent periods

If you have any of these, conditions such as polycystic ovary syndrome (PCOS), endometriosis, or thyroid disease may be involved, and a medical visit is in order.

Intermenstrual Bleeding

Unlike spotting, intermenstrual bleeding is heavier and unexpected between regular periods. It may be from bright red to dark brown and can contain blood clots.

Possible Causes of Bleeding Between Periods

Sexually Transmitted Infections (STIs): Chlamydia and gonorrhea can lead to inflammation and abnormal bleeding.

Pelvic Inflammatory Disease (PID): A bacterial infection of the reproductive organs and can lead to abnormal bleeding.

Uterine Fibroids or Polyps: Benign growths in the uterus that may cause unexpected bleeding.

Endometrial Hyperplasia or Cancer: In some instances, abnormal bleeding may be a sign of abnormal cell growth in the lining of the uterus.

When to See a Doctor

See a doctor if intermenstrual bleeding is:

• Frequent or persistent
• Associated with pelvic pain or discomfort
• Associated with abnormal discharge, fever or painful sex

Recognizing your body's rhythms can assist you in identifying normal versus abnormal bleeding. Monitoring your menstrual cycle through an app or calendar may flag changes that should be checked with a doctor. If you have any questions regarding abnormal bleeding, visiting your health care provider is the way to go.

Spending hours sitting at a desk, gaming or binge-watching shows without moving may increase the risk of blood clots, including deep vein thrombosis (DVT), vascular experts have warned.

Prolonged sitting slows blood flow from the legs, potentially increasing the risk of clot formation. Experts from the Vascular Society of India (VSI) highlighted the concern at the VSI-ASVS 2026 Conference, noting that sedentary screen habits warrant attention even among young, otherwise healthy people.

“In our OPD, we are seeing patients where lifestyle history has become an important part of the vascular evaluation. Earlier, when we thought about prolonged immobility, we primarily discussed long-distance travel, hospitalization or being bedridden. Today, we also need to ask young patients how many hours they spend continuously sitting in front of a gaming console, computer or OTT screen,” said Dr. Tarun Grover, Senior Director of Peripheral Vascular and Endovascular Sciences at Medanta.

What Is DVT?

Deep vein thrombosis (DVT) occurs when a blood clot forms in a deep vein, usually in the legs. If the clot travels to the lungs, it can cause a potentially life-threatening pulmonary embolism.

Although prolonged immobility has traditionally been associated with long-distance travel, hospitalization and bed rest, experts say extended screen time can also contribute to inactivity.

Gaming and binge-watching do not automatically cause DVT. However, prolonged sitting may add to the risk, particularly in people with obesity, dehydration, smoking habits, hormonal risk factors, inherited clotting disorders or a previous history of thrombosis.

What Does Science Say?

A 2024 systematic review and dose-response meta-analysis published in Scientific Reports, covering 25 articles and 31 studies, found that people with the highest levels of sedentary behavior had approximately 24% higher risk of venous thromboembolism (VTE) than those with the lowest levels.

The analysis also found a 2% increase in VTE risk for every additional hour of sedentary behavior per day. The association persisted after accounting for physical activity, suggesting that exercise may not fully offset the potential risks of prolonged sitting.

The experts explained that when people sit for hours, their calf muscles—which help pump blood back toward the heart—remain relatively inactive, slowing venous circulation.

A separate study of 11 adolescents with thrombosis found that all reported at least four hours of daily screen exposure, averaging approximately six hours. Eight had DVT in the legs, two had pulmonary embolism and one had subclavian vein thrombosis.

Many also had inherited thrombophilia, a predisposition to blood clots. Researchers noted that prolonged screen-related inactivity may act as an additional trigger rather than the sole cause of thrombosis.

“The evidence showing a 24% higher VTE risk with higher sedentary exposure should make us take this issue seriously. A young age should not create a false sense of security, particularly when prolonged sitting is combined with other risk factors,” Dr. Grover said.

How Can You Reduce The Risk?

Experts recommend taking regular movement breaks during work, gaming and streaming sessions to avoid prolonged uninterrupted sitting.

“Just as smoking increases vascular and clotting risks, prolonged sitting can also increase the risk of blood clots. When a person remains seated for hours, the calf-muscle pump becomes inactive, venous blood flow from the legs slows down and blood can stagnate in the deep veins," said Dr. Bhupesh Garg, Senior Vascular and Endovascular Surgeon, Vascular Society of India.

The message should be simple: if you are going to spend hours on a screen, do not spend those hours completely still, the experts said.

The Black Death swept across Eurasia and North Africa between 1346 and 1353, killing an estimated 30% to 60% of Europe's population.

Plague continued to recur in Europe over subsequent centuries, causing millions of deaths. Caused by Yersinia pestis, the same bacterium responsible for plague today, the Black Death was primarily associated with bubonic plague, although pneumonic plague also occurred.

Bubonic plague typically spreads through infected flea bites, while pneumonic plague affects the lungs and can spread between people through infectious respiratory particles during close contact. All forms can be fatal without prompt treatment, but antibiotics are effective when administered early.

India's 1994 Plague Outbreak

Although often associated with medieval history, plague continues to occur in parts of the world.

In 1994, India experienced an outbreak involving both bubonic and pneumonic plague, following heavy flooding and reports of exposure to dead rats.

“When the plague outbreak happened in India, I was one of the people who investigated it. The outbreak involved bubonic plague, which can be treated with antibiotics, and Surat also saw 64 to 68 cases of pneumonic plague. We identified the plague bacillus and traced its cycle in the surrounding wildlife. Plague surveillance in rats and other animals is essential to detect outbreaks early and take preventive measures,” Dr. N.K. Ganguly, former Director General of the Indian Council of Medical Research (ICMR), told HealthandMe.

There were 693 suspected cases that tested positive for Yersinia pestis antibodies and 56 deaths nationwide.

Surveillance, hygiene and timely treatment were essential to controlling the disease, said Dr. Amitabh Banerjee, an epidemiologist and former member of the Indian Armed Forces’ mobile epidemic investigation team. He investigated the 2002 pneumonic plague outbreak in Himachal Pradesh, which caused 16 cases and four deaths.

Plague Still Exists In Africa And The US

In the US, an average of about seven human plague cases are reported annually, mostly in rural areas of the American West, according to the Centers for Disease Control and Prevention (CDC).

The continued presence of Yersinia pestis in animal populations means the disease has not been eradicated.

“People think the plague is gone, it was something that occurred 500 years ago. It's not. It's here amongst us,” Simon Clarke of the University of Reading in the UK told the Associated Press. “Unless you get rid of those wild animals, which of course is not possible, then you're not going to get rid of the bacteria.”

Russia's Plague Scare: What We Know

Russia has completed checks following the October 2 death of 28-year-old laboratory worker Darya Shipilova in Siberia. Authorities have not confirmed plague as the cause, describing her illness as pneumonia of unknown origin. Nearly 5,000 samples reportedly showed no dangerous pathogens.

Reports of a second death linked to the plague was called "fake news" by Russia, and no plague outbreak has been confirmed in Russia. The WHO and US have requested Russia for more transparency regarding the cases.

Can Plague Be Eradicated?

Plague persists because Yersinia pestis circulates naturally among wild and domestic animals, including rodents, and their fleas. Eliminating human cases in one location does not remove the bacterium from these animal reservoirs.

Dr. Banerjee said plague can be deadly, particularly when it affects the lungs, but modern antibiotics are highly effective when treatment begins early.

“Plague cannot be eradicated because it is in wildlife, it is in rodents and all. So the only thing is hygiene and, with modern antibiotics, there should not be any panic,” he told HealthandMe.

Bubonic plague does not typically spread directly between people, while pneumonic plague can spread through infectious respiratory particles during close contact. Pneumonic plague can progress rapidly and requires urgent treatment.

Dr. Banerjee cautioned against assuming that a suspected case automatically signals a wider outbreak, noting that early diagnosis and appropriate antibiotic treatment are crucial.

Indian jewelery designer Saba Ali Khan, daughter of veteran actress Sharmila Tagore and cricketer Mansoor Ali Khan Pataudi, has opened up about her brain tumor diagnosis at the age of 27.

Speaking on her sister, actress Soha Ali Khan’s podcast, Saba recalled that her diagnosis came as a surprise, without common warning signs such as headaches or vision loss.

Dr. Mazda K. Turel, the neurosurgeon who treated her at Wockhardt Hospitals, Mumbai, told HealthandMe that people with brain tumors can be “walking, talking and functioning normally” despite having a potentially serious tumor. He explained why tumors can go unnoticed and which symptoms warrant medical attention.

How Saba Ali Khan Discovered Her Brain Tumor

Saba recalled fainting while out with a friend. After losing consciousness a second time, she took around 20–25 minutes to regain consciousness.

An MRI revealed a shadow in the third ventricle of her brain. Doctors initially diagnosed a colloid cyst, a rare, non-cancerous growth.

Six months later, she underwent surgery and was diagnosed with pilocytic astrocytoma, a slow-growing, generally low-grade tumor of the brain or spinal cord.

Why Brain Tumours Go Undetected In Young Adults

“Brain tumors don’t check your age before making an appearance,” Dr. Turel said. “In young adults, symptoms are often dismissed as stress, migraines, fatigue or lack of sleep. Some tumors grow slowly, allowing the brain to adapt remarkably well.”

“The brain has an extraordinary ability to compensate, especially when a tumor grows slowly or develops in a relatively silent area,” he explained.

Early signs may include persistent headaches, subtle personality changes, difficulty concentrating, blurred vision and unexplained seizures. Other clues include forgetting familiar words, unexplained irritability, occasional imbalance and brief episodes of staring or losing awareness.

Sometimes, family members notice changes before the patient does. Dr. Turel illustrated the difference between ordinary forgetfulness and a potentially concerning change: “If you forget keys, that is OK, but if you forget what the keys are for,” it is a sign to get checked.

“The problem is that these symptoms are common, but their persistence or progression is what deserves attention,” he told HealthandMe.

Symptoms often depend more on where a tumor is located than on its size, Dr. Turel explained.

• Frontal lobe: Changes in personality or judgement.
• Temporal lobe: Memory problems or unusual seizures.
• Visual pathways: Blurred or double vision.
• Cerebellum: Problems with balance and coordination.

“New speech difficulties, weakness, unexplained seizures or progressive cognitive changes should never be casually dismissed,” he warned.

Brain Tumor Or Migraine: When Should A Headache Worry You?

Migraines usually follow a recognizable pattern and may involve nausea or sensitivity to light and sound, Dr. Turel said.

Tumor-related headaches are more concerning when they are new, progressively worsening, different from previous headaches or accompanied by neurological changes. They may be worse in the morning or with coughing and straining, although this is not always the case.

A persistent headache that progressively worsens, wakes someone from sleep or occurs with vomiting, visual changes or neurological symptoms warrants medical evaluation.

"A sudden, explosive headache that reaches maximum intensity within seconds—a thunderclap headache—is a medical emergency," the neurosurgeon said, noting that it can occur while "walking, talking and functioning normally"

It may indicate bleeding around the brain from a ruptured aneurysm rather than a tumor. Sudden weakness, confusion, loss of consciousness or a first seizure also require emergency assessment.

“Most headaches are not caused by brain tumors, and a headache alone rarely indicates one. The key is not to panic about every headache, but to recognize when an old familiar headache begins behaving like a stranger,” Dr. Turel said.
