What is abnormal vaginal bleeding?

Vaginal bleeding is normal during monthly periods. Abnormal vaginal bleeding means bleeding that happens outside of what is usual for you — at unexpected times, in unexpected amounts, or after menopause. It is one of the most important symptoms to tell a doctor about, because it can be an early sign of cervical or uterine cancer — as well as many other treatable conditions.

Discussing gynaecological symptoms with a doctor can feel uncomfortable, but it is essential. All consultations are private and confidential. Finding a problem early always leads to better outcomes.

When is vaginal bleeding a warning sign?

The following types of abnormal bleeding always need medical evaluation:

  • Bleeding after menopause — menopause means you have not had a period for 12 or more consecutive months. Any bleeding after this point is abnormal — there is no normal reason to bleed after menopause. See a doctor promptly
  • Bleeding between periods (spotting) — bleeding that happens in the middle of your cycle and is not part of your normal pattern
  • Bleeding after sex (post-coital bleeding) — this is a classic early warning sign of cervical cancer and should always be evaluated
  • Unusually heavy periods — periods significantly heavier than your normal, lasting longer than 7 days, or causing you to change a pad or tampon more often than every 1–2 hours
  • Unusual vaginal discharge — watery, blood-tinged, or foul-smelling discharge is abnormal and needs evaluation
  • Pelvic pain — ongoing pain or pressure in the lower abdomen or pelvis, unrelated to periods

Any of these symptoms should be reported to a doctor. You do not need to wait to see if they go away.

Other possible causes

Abnormal bleeding is not always caused by cancer. Many common and treatable conditions can cause it:

  • Hormonal changes — fluctuating hormone levels, especially around perimenopause or if you use hormonal contraception
  • Uterine fibroids — non-cancerous growths in the uterus, very common, can cause heavy or prolonged periods
  • Polyps — small growths inside the uterus or cervix that can cause spotting or irregular bleeding
  • Infections — sexually transmitted infections and other gynaecological infections can cause bleeding and discharge
  • Thyroid problems — an underactive or overactive thyroid can disturb the menstrual cycle
  • Pregnancy-related causes — unexpected pregnancy, ectopic pregnancy, or miscarriage can cause abnormal bleeding

Even if you think your bleeding has a harmless cause, cancer must be ruled out — especially if you are over 40 or have had any bleeding after menopause.

Warning signs that need prompt attention

See a doctor within a week if you have:

  • Any vaginal bleeding after menopause
  • Bleeding after sex (even once)
  • Bleeding between periods that happens regularly
  • Very heavy periods soaking more than one pad per hour for several hours in a row
  • Unusual vaginal discharge that is blood-tinged, watery, or has a bad smell

See a doctor the same day or go to an emergency department if you have:

  • Extremely heavy bleeding that is soaking through several pads an hour and not slowing down
  • Severe pelvic pain together with heavy bleeding
  • Bleeding during pregnancy (this requires immediate evaluation)

What a doctor will do

A doctor or gynaecologist will begin with a careful assessment:

  1. Medical history — when the bleeding started, how much, any other symptoms, and your period and pregnancy history
  2. Pelvic examination — the doctor will gently examine the vulva, vagina, and cervix. This may feel uncomfortable but should not be painful and takes only a few minutes
  3. Pap smear — a simple test where cells are gently scraped from the cervix and sent to a laboratory. Combined with an HPV test, it is the main screening test for cervical cancer
  4. HPV test — tests for the presence of high-risk human papillomavirus (HPV), which causes almost all cervical cancers
  5. Colposcopy — if the Pap smear or HPV test is abnormal, the doctor uses a special magnifying instrument to look closely at the cervix. Tiny biopsies may be taken from any suspicious areas
  6. Transvaginal ultrasound — for evaluating the uterus; checks the thickness of the uterine lining (endometrium), which can indicate uterine cancer when thickened after menopause
  7. Uterine biopsy (endometrial biopsy) — if uterine cancer is suspected, a small tissue sample is taken from the lining of the uterus

A Pap smear and HPV test are available at AIIMS Patna and Mahavir Cancer Sansthan. Many government hospitals and primary health centres in Bihar now offer basic gynaecological evaluation.

HPV vaccination — preventing cervical cancer

Most cases of cervical cancer are caused by persistent HPV infection — and this is preventable. The HPV vaccine is highly effective when given before exposure to the virus. It is recommended for girls aged 9 to 14 years. In India, the government HPV vaccination programme is being expanded. If you have a daughter in this age range, talk to a health worker or doctor about getting her vaccinated.

A note for women in Bihar

Many women in Bihar delay seeking help for gynaecological symptoms because they feel embarrassed, are not sure if the symptom is serious, or are worried about what others will think. These concerns are understandable, but waiting can be dangerous.

Cervical cancer grows slowly — when caught early, it is highly treatable and often curable. Bleeding after menopause or after sex is not something to ignore or keep to yourself. The gynaecology outpatient department at any government hospital or private clinic handles these concerns every day and will treat you with respect and privacy.

You do not need to explain your reason for seeking care to anyone other than your doctor.
