Vaginal or uterine bleeding - overview

Vaginal bleeding normally occurs during a woman's menstrual cycle, when she gets her period. Every woman's period is different.

• Most women have cycles between 24 and 34 days apart. It usually lasts 4 to 7 days in most cases.
• Young girls may get their periods anywhere from 21 to 45 days or more apart.
• Women in their 40s will often notice their period occurring less often.

Many women have abnormal bleeding between their periods at some point in their lives. Abnormal bleeding occurs when you have:

• Heavier bleeding than usual
• Bleeding for more days than normal (menorrhagia)
• Spotting or bleeding between periods
• Bleeding after sex
• Bleeding after menopause
• Bleeding while pregnant
• Bleeding before age 9
• Menstrual cycles longer than 35 days or shorter than 21 days
• No period for 3 to 6 months (amenorrhea)

Causes

There are many causes of abnormal vaginal bleeding.

HORMONES

Abnormal bleeding is often linked to failure of regular ovulation (anovulation). Doctors call the problem abnormal uterine bleeding (AUB) . AUB is more common in teenagers and in women who are approaching menopause.

Women who take oral contraceptives may experience episodes of abnormal vaginal bleeding. Often this is called "breakthrough bleeding." This problem often goes away on its own. However, talk to your health care provider if you have concerns about the bleeding.

Bleeding from the rectum or blood in the urine may be mistaken for vaginal bleeding. To know for certain, insert a tampon into the vagina and check for bleeding.

Keep a record of your symptoms and bring these notes to your doctor. Your record should include:

• When menstruation begins and ends
• How much flow you have (count numbers of pads and tampons used, noting whether they are soaked)
• Bleeding between periods and after sex
• Any other symptoms you have

Exams and Tests

Your provider will perform a physical exam, including a pelvic exam. Your provider will ask questions about your medical history and symptoms.

You may have certain tests, including:

• Pap test
• Urinalysis
• Thyroid functioning tests
• Complete blood count (CBC)
• Iron count
• Pregnancy test

Based on your symptoms, other tests may be needed. Some can be done in your provider's office. Others may be done at a hospital or surgical center:

• Sonohysterography: Fluid is placed in the uterus through a thin tube, while vaginal ultrasound images are made of the uterus.
• Ultrasound: Sound waves are used to make a picture of the pelvic organs. The ultrasound may be performed abdominally or vaginally. 
• Magnetic resonance imaging (MRI): In this imaging test, powerful magnets are used to create images of internal organs.
• Hysteroscopy : A thin telescope-like device is inserted through the vagina and the opening of the cervix. It lets the provider view the inside of the uterus.

Treatment may include hormonal medicines, pain relievers, and possibly surgery.

The type of hormone you take will depend on whether you want to get pregnant as well as your age.

• Birth control pills can help make your periods more regular.
• Hormones also can be given as an injection, a skin patch, a vaginal cream, or through an IUD that releases hormones.
• An IUD is a birth control device that is inserted in the uterus. The hormones in the IUD are released slowly and may control abnormal bleeding.

Other medicines given for abnormal uterine bleeding may include:

• Nonsteroidal anti-inflammatory drugs (ibuprofen or naproxen) to help control bleeding and reduce menstrual cramps
• Tranexamic acid to help treat heavy menstrual bleeding
• Antibiotics to treat infections

When to Contact a Medical Professional

Call your provider if:

• You have soaked through a pad or tampon every hour for 2 to 3 hours.
• Your bleeding lasts longer than 1 week.
• You have vaginal bleeding and you are pregnant or could be pregnant.
• You have severe pain, especially if you also have pain when not menstruating.
• Your periods have been heavy or prolonged for three or more cycles, compared to what is normal for you.
• You have bleeding or spotting after reaching menopause.
• You have bleeding or spotting between periods or caused by having sex.
• Abnormal bleeding returns.
• Bleeding increases or becomes severe enough to cause weakness or lightheadedness.
• You have fever or pain in the lower abdomen
• Your symptoms become more severe or frequent.

Prevention

Aspirin may prolong bleeding and should be avoided if you have bleeding problems. Ibuprofen most often works better than aspirin for relieving menstrual cramps. It also may reduce the amount of blood you lose during a period.
