Vaginal Bleeding Symptoms

Many women of child-bearing age have experienced symptoms of vaginal bleeding and thought, "it must be that time of the month again." However, at times, symptoms of vaginal bleeding should make women in this age range stop and think "…. or is it?"

Vaginal bleeding symptoms can be normal or abnormal [1, 17]. Normal vaginal bleeding (menstruation) happens every 21 to 35 days. The bleeding occurs because the uterus sheds its lining, and a new reproductive cycle begins. Vaginal bleeding symptoms unrelated to a normal menstrual cycle are considered abnormal.

The definition of a "normal menstrual cycle" is different for every woman [2, 17]. A menstrual cycle for one woman may last for a few days but for another woman may last a week or more. Be cautious of symptoms of vaginal bleeding that are different from your regular pattern.

For example, abnormal patterns of vaginal bleeding include bleeding that:

  • Is lighter or heavier than your normal flow [1]
  • Occurs when you are not expecting your menstrual period
  • Occurs during a time in your life when it is not expected such as before puberty, during pregnancy or after menopause (which is defined as 12 or more consecutive months without a menstrual period).

Being able to recognize patterns of vaginal bleeding that stray outside of your normal menstrual cycle is very important. You should always seek medical care and follow up with your doctor if you experience symptoms of abnormal vaginal bleeding [13].

Vaginal Bleeding Causes

The causes of vaginal bleeding are numerous [3, 17], and the list can seem daunting. However, not all abnormal vaginal bleeding indicates a serious condition. This is why it is important to see your doctor in order to evaluate the cause of your symptoms and receive proper treatment.

Pregnancy-related factors:

  • Consider possible pregnancy if you experience abnormal vaginal bleeding symptoms. The bleeding can signify a pregnancy or problems with a pregnancy such as miscarriage or ectopic pregnancy [7, 21].


  • Bacterial Infections: Infections such as chlamydia and gonorrhea can infect the reproductive tract and cause irritation and inflammation, especially after sexual intercourse, that can result in abnormal vaginal bleeding and other STD symptoms in women [3].
  • Fungal Infections: Fungal infections such as yeast also often affect the vaginal canal and result in inflammation that results in bleeding.

Benign uterine conditions:

  • Obstruction: Sometimes abnormal vaginal bleeding can be caused by masses in the reproductive organs such as fibroids that are not cancerous.

    • Hormonal Imbalances: Conditions of the uterus that occur as a result of hormonal imbalances such endometriosis and adenomyosis can result in heavy periods that are not your usual pattern [9, 20].

Medications and medical devices:

  • Contraceptives methods: Birth control pills can cause vaginal bleeding symptoms if they are not used properly [14, 17]. Abnormal vaginal bleeding is also a known side effect of Intrauterine devices (IUDs).
  • Medications: Medications such as blood thinners can cause you to bleed more during your menstrual cycle.

Blood disorders:

  • Functional: Medical conditions such as von Willebra disease (clotting disorder) that affect the way different components of your blood function can result in vaginal bleeding [3].
  • Synthetic: Your liver and to lesser extent your kidney are organs that are very important in making the components of your blood that regulate bleeding. If there is a malfunction in these organs such as liver disease or kidney disease, you may experience abnormal vaginal bleeding as well.


  • Vaginal bleeding in women who have started menopause may be caused by cancers of any part the reproductive tract such as the ovary, vagina and uterus.
  • There is also a precancerous condition called endometrial hyperplasia that can cause abnormal vaginal bleeding.

Endocrine system factors:

  • Hormone imbalances such as Polycystic Ovarian Syndrome (PCOS) can interfere with your normal menstrual cycle and cause abnormal vaginal bleeding [6].


  • Blunt trauma, penetrating injury to the vagina/cervix and sexual abuse can all cause vaginal bleeding [3].
  • A retained tampon (multiple days) can also lead to trauma that results in vaginal bleeding.

9 Possible Conditions

The list below shows results from the use of our quiz by Buoy users who experienced vaginal bleeding. This list does not constitute medical advice and may not accurately represent what you have.

  1. 1.Normal Case of Spotting

    Spotting is vaginal bleeding that occurs between periods. Many women experience spotting between periods and it is often nothing to worry about. Oral contraceptives (the pill) can cause spotting as a side effect, especially if they have a low estrogen dose, someone started on them recently or does not take them on the same time everyday. Additionally, hormone supplements that only contain estrogen (often used in menopause) can cause spotting as well.

    A few days

    Top Symptoms:
    vaginal bleeding or bloody discharge, bloody vaginal discharge, mild unexpected vaginal bleeding, vaginal bleeding, vaginal discharge
    Symptoms that always occur with normal case of spotting:
    vaginal bleeding or bloody discharge

  2. 2.Ovulation Pain (Mittelschmerz) or Midcycle Spotting

    Mittelschmerz, also known as ovulation pain or mid-cycle pain, is abdominal pain that occurs around the time the egg is released from an ovary. Ovulation can sometimes cause some mild vaginal bleeding, spotting or blood-stained/brown discharge as well.

    As ovulation occurs monthly, it's possible you will experience this pain once a month.

    Top Symptoms:
    abdominal pain (stomach ache), last period approximately 2 weeks ago, vaginal bleeding, bloody vaginal discharge, pelvis pain
    Symptoms that always occur with ovulation pain (mittelschmerz) or midcycle spotting:
    last period approximately 2 weeks ago
  3. 3.Polycystic Ovary Syndrome

    Polycystic ovary syndrome is a common hormone disorder characterized by irregular periods, acne, and fertility issues.

    Symptoms are well controlled with medicines including combined hormonal birth control.

    Top Symptoms:
    fatigue, vaginal bleeding, pelvis pain, depressed mood, painful periods
    Symptoms that always occur with polycystic ovary syndrome:
    oligo/amenorrhea or hyperandrogenism
    Primary care doctor
  4. 4.Ectopic Pregnancy

    Ectopic pregnancy occurs when the fertilized egg implants outside of the uterus. The vast majority of ectopic pregnancies occur in the fallopian tubes.

    Treatment depends on how far the pregnancy has progressed but in all cases leads to the termination of the embryo.

    Top Symptoms:
    abdominal pain (stomach ache), nausea or vomiting, vaginal bleeding, pelvis pain, moderate abdominal pain
    Symptoms that never occur with ectopic pregnancy:
    disapearance of periods for over a year
    Hospital emergency room

Vaginal Bleeding Treatments, Relief and Prevention

Vaginal bleeding can be discomforting and distressing even during a normal menstrual cycle. Seeking prompt medical attention when you notice symptoms of abnormal bleeding will accelerate your diagnosis and allow you to get the appropriate treatment. Your treatment will depend on the cause of your symptoms and the results of any testing.


  • Hormones: Many uterine conditions and endocrine system causes of abnormal bleeding are the result of an imbalance of hormones in the body [15]. Your doctor may prescribe treatment in the form of these hormones in order to restore your body's balance [16, 17].
  • Antibiotics: Your doctor may prescribe antibiotics for certain infections of the reproductive tract that may cause your vaginal bleeding symptoms.
  • Changes to your current regimen: If contraceptive methods or other medications are contributing to your symptoms, your doctor may discuss stopping your current medications in favor of a new regimen [14].
  • Other treatment: If your vaginal bleeding symptoms are caused by an underlying bleeding disorder or systemic disease, your doctor will treat the primary disease first and monitor its effects on your vaginal bleeding.


  • When medications fail some causes of vaginal bleeding can be treated with surgical options that either remove masses or decrease the lining of the uterus [18, 19]. Most cancers of the reproductive organs are removed by surgery [18].

Pregnancy care:

  • If your bleeding is caused by pregnancy-related factors your doctor will discuss available options for care [21].

Seek immediate medical attention if:

  • You have sudden, severe pain in your belly or pelvis area
  • You are soaking through your usual pads or tampons every hour for 2 or more hours.
  • You feel dizzy or lightheaded, or you feel like you may faint.

FAQs About Vaginal Bleeding

Here are some frequently asked questions about vaginal bleeding.

Can stress cause vaginal bleeding?

No, stress cannot cause vaginal bleeding. Stress can, however, cause an earlier or later menstrual cycle and cause bleeding in-line with a new cycle [22]. If you have new mid-cycle bleeding and have not consulted a clinician, you should seek medical evaluation. It may be a sign of anything from a sexually transmitted infection (STI), to fibroids, to a pregnancy, or it may have no definable cause [13, 14, 15].

Why am I bleeding between my periods?

Bleeding between periods can be caused by serious or benign causes. The most dangerous causes often involve pregnancy. A failed pregnancy, a pregnancy in which the egg implants in the fallopian tube, disconnection of the placenta from the uterus, or damage to the uterus can all cause bleeding. If you suspect any of these causes, you should seek medical evaluation as soon and as safely as possible. Otherwise, uterine fibroids, tumor, blood thinners, ruptured ovarian cysts and gynecological infections, and changes in contraceptive drugs can cause spotting [4, 13, 14].

Is vaginal bleeding an early sign of pregnancy?

No, vaginal bleeding is not an early sign of normal pregnancy [15, 21]. If you are pregnant and experience vaginal bleeding, you should visit your OBGYN for evaluation. Vaginal bleeding can be caused by many things other than pregnancy, including sexually transmitted infections, uterine growths called fibroids, and certain types of cancers [4, 13, 14, 15].

Why am I still spotting after my period ends?

Continuous bleeding after a period can be caused by a many things [17, 23]. Most commonly, an abnormally long period may have no discernible cause [14, 15]. If it does not recur, it may require no further investigation. Continuous spotting may be a sign of a disorder in coagulation caused by either medication or a genetic disorder. It may also be a sign of infection of the vagina or cervix.

Why am I experiencing vaginal bleeding after menopause?

Vaginal bleeding after menopause may be due to medications, hyperplasia of the uterus, or some types of uterine cancer [24]. Certain medications containing estrogen or progesterone can cause either hyperplasia or an increase in the amount of tissue in the uterus, which may cause bleeding or an excess sloughing off of tissue — both of which will be seen as vaginal bleeding.
