Abnormal Vaginal BleedingSkip to the navigation
Many women experience abnormal vaginal bleeding or spotting between periods sometime in their lives. Vaginal bleeding is considered to be abnormal if it occurs:
- When you are not expecting your menstrual period.
- When your menstrual flow is lighter or heavier than what is normal for you.
- At a time in life when it is not expected, such as before age 9, when you are pregnant, or after menopause.
Causes of abnormal bleeding
Abnormal vaginal bleeding has many possible causes. By itself, it does not necessarily indicate a serious condition.
- Because bleeding can mean a problem with
pregnancy, possible pregnancy should always be considered in a woman of
- Spotting to minimal bleeding may be normal. But any bleeding during pregnancy needs to be evaluated by your doctor.
- Heavy vaginal bleeding or bleeding that occurs before 12 weeks may mean a serious problem, including an ectopic pregnancy or miscarriage.
- Heavy vaginal bleeding or bleeding that occurs after 12 weeks also may mean a serious problem, such as placenta previa.
- Ovulation can cause mid-cycle bleeding.
- Polycystic ovary syndrome (PCOS) is a hormone imbalance that interferes with normal ovulation and can cause abnormal bleeding.
- Medicines, such as birth control pills, sometimes cause abnormal vaginal bleeding. You may have minor bleeding between periods during the first few months if you have recently started using birth control pills. You also may have bleeding if you do not take your pills at a regular time each day. For more information, see the topic Birth Control.
- An intrauterine device (IUD) also may increase your chances of spotting or heavy periods. For more information on the IUD, see the topic Birth Control.
- Infection of the pelvic organs (vagina, cervix, uterus, fallopian tubes, or ovaries) may cause vaginal bleeding, especially after intercourse or douching. Sexually transmitted infections (STIs) are often the cause of infections. For more information, see the topic Sexually Transmitted Infections.
- Pelvic inflammatory disease (PID) causes inflammation or infection of the uterus, fallopian tubes, or ovaries, which can cause abnormal bleeding.
Other less common causes of abnormal vaginal bleeding that may be more serious include:
- Sexual abuse.
- An object in the vagina.
- Uterine fibroids, which are a common cause of heavy periods. For more information, see the topic Uterine Fibroids.
- Structural problems, such as urethral prolapse or polyps.
- Cancer of the cervix, uterus, ovaries, or vagina.
- Extreme emotional stress and excessive exercise. But excessive exercise more frequently causes an absence of menstruation (amenorrhea).
- Other diseases, such as hyperthyroidism or diabetes.
Heavy bleeding during the first few weeks after delivery (postpartum) or after an abortion may occur because the uterus has not contracted to the prepregnancy size or because fetal tissue remains in the uterus (retained products of conception).
If you are age 40 or older, abnormal vaginal bleeding may mean that you are entering perimenopause. In a woman who has not had a menstrual period for 12 months, vaginal bleeding is always abnormal and should be discussed with your doctor.
Treatment of abnormal vaginal bleeding depends on the cause of the bleeding.
Check your symptoms to decide if and when you should see a doctor.
Check Your Symptoms
Many things can affect how your body responds to a symptom and what kind of care you may need. These include:
- Your age. Babies and older adults tend to get sicker quicker.
- Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
- Medicines you take. Certain medicines, herbal remedies, and supplements can cause symptoms or make them worse.
- Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
- Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.
Shock is a life-threatening condition that may quickly occur after a sudden illness or injury.
Symptoms of shock (most of which will be present) include:
- Passing out.
- Feeling very dizzy or lightheaded, like you may pass out.
- Feeling very weak or having trouble standing.
- Not feeling alert or able to think clearly. You may be confused, restless, fearful, or unable to respond to questions.
Pain in adults and older children
- Severe pain (8 to 10): The pain is so bad that you can't stand it for more than a few hours, can't sleep, and can't do anything else except focus on the pain.
- Moderate pain (5 to 7): The pain is bad enough to disrupt your normal activities and your sleep, but you can tolerate it for hours or days. Moderate can also mean pain that comes and goes even if it's severe when it's there.
- Mild pain (1 to 4): You notice the pain, but it is not bad enough to disrupt your sleep or activities.
Many prescription and nonprescription medicines can cause changes in vaginal bleeding. A few examples are:
- Anticoagulant medicines used to prevent blood clots, such as warfarin (Coumadin) and aspirin.
- Corticosteroids, such as prednisone.
- Hormone therapy.
- Thyroid medicines.
Severe vaginal bleeding means that you are soaking 1 or 2 pads or tampons in 1 or 2 hours, unless that is normal for you. For most women, passing clots of blood from the vagina and soaking through their usual pads or tampons every hour for 2 or more hours is not normal and is considered severe. If you are pregnant: You may have a gush of blood or pass a clot, but if the bleeding stops, it is not considered severe.
Moderate bleeding means that you are soaking more than 1 pad or tampon in 3 hours.
Mild bleeding means that you are soaking less than 1 pad or tampon in more than 3 hours.
Minimal vaginal bleeding means "spotting" or a few drops of blood.

There is no home treatment for abnormal vaginal bleeding. With some types of vaginal bleeding, it may be okay to wait to see if the bleeding stops on its own. Check your symptoms to decide if and when you should see a doctor. If the bleeding continues or gets worse, see your doctor to find out the reason for the bleeding.
If you are using tampons for abnormal vaginal bleeding, be sure to change them often, and do not leave one in place when the bleeding has stopped. A tampon left in the vagina may put you at risk for toxic shock syndrome (TSS). TSS is a rare but life-threatening illness that develops suddenly after a bacterial infection rapidly affects several different organ systems.
Symptoms to watch for during home treatment
Call your doctor if any of the following occur during home treatment:
- Abnormal bleeding returns.
- Bleeding increases or becomes severe enough to cause weakness or lightheadedness.
- Fever or pain in the lower abdomen develops.
- Symptoms become more severe or frequent.
You may be able to prevent abnormal vaginal bleeding.
- Maintain a healthy weight. Women who are overweight or underweight have more problems with abnormal vaginal bleeding. For more information, see the topic Weight Management.
- If you are using birth control pills, be sure to take them as directed and at the same time every day. For more information, see the topic Birth Control.

- Learn to practice relaxation exercises to reduce and cope with stress. Stress may cause abnormal vaginal bleeding. For more information, see the topic Stress Management.
- Take a
nonsteroidal anti-inflammatory drug (NSAID), such as
naproxen or ibuprofen. NSAIDs reduce menstrual bleeding by decreasing the
production of substances called prostaglandins. The usual recommended dose of
ibuprofen is 400 mg every 6 hours. Begin taking the medicine on the first day
of your period and continue taking it until your menstrual bleeding stops. Be
sure to follow these nonprescription medicine precautions.
- Carefully read and follow all label directions on the medicine bottle and box.
