Bleeding Between Periods: Causes, Warning Signs and When to See a Gynaecologist
Unexpected spotting or vaginal bleeding can be worrying. Learn about possible causes, important warning signs and when to seek specialist gynaecological advice.
Noticing blood or spotting when you are not expecting your period can be concerning. Whether it is light pink spotting, brown discharge or bleeding resembling a period, unexpected vaginal bleeding deserves attention.
Bleeding between periods, medically called intermenstrual bleeding, can have several causes. Some are related to hormonal changes or contraception, while others may involve fibroids, polyps, infections or cervical conditions.
At Gynaeaesthetics London, Consultant Gynaecologist Mr Mohammad Masood provides personalised assessment and care for women's health concerns.
What Is Bleeding Between Periods?
Bleeding between periods refers to vaginal bleeding occurring outside your expected menstrual period.
It may appear as:
- Light pink or red spotting
- Brown discharge containing old blood
- Bleeding after sexual intercourse
- Unexpected bleeding halfway through your cycle
- Repeated episodes of irregular vaginal bleeding
Although some women experience occasional light spotting around ovulation, unexplained or recurring bleeding should not automatically be considered normal.
7 Possible Causes of Bleeding Between Periods
1. Hormonal Changes
Changes in oestrogen and progesterone can affect the lining of the uterus and cause unexpected spotting. Hormonal fluctuations may occur during puberty, perimenopause or irregular menstrual cycles.
Women experiencing changes in their periods alongside hot flushes, sleep difficulties or mood changes may benefit from exploring menopause and HRT care at Gynaeaesthetics London.
2. Hormonal Contraception
Spotting may occur when starting or changing hormonal contraception, including the combined pill, progestogen-only pill, contraceptive implant or hormonal intrauterine system.
This is sometimes known as breakthrough bleeding. Persistent or new bleeding should be reviewed, particularly when contraception has remained unchanged.
3. Uterine Fibroids
Fibroids are non-cancerous growths that develop in or around the uterus. Depending on their size and location, they can contribute to heavy periods, pelvic pressure and bleeding between periods.
Fibroids affecting the uterine cavity are particularly associated with abnormal bleeding.
Learn more about fibroid symptoms, diagnosis and treatment.
4. Uterine or Cervical Polyps
Polyps are growths that develop from the lining of the womb or cervix. Most are benign, but some may cause spotting, irregular bleeding or bleeding after intercourse.
Depending on your symptoms, your gynaecologist may recommend ultrasound imaging, hysteroscopy or other appropriate investigations.
5. Cervical Changes
Cervical ectropion, inflammation, infections and abnormal cervical cells can sometimes cause unexpected bleeding, especially after sexual intercourse.
Cervical screening identifies people at risk of cervical cancer, but it is not a diagnostic test for unexplained bleeding. Further assessment may include colposcopy.
Read about abnormal cervical screening and colposcopy.
6. Infection or Inflammation
Certain infections, including sexually transmitted infections such as chlamydia, may cause bleeding between periods or after intercourse.
Other symptoms can include unusual vaginal discharge, pelvic discomfort or pain when passing urine. Some infections cause no obvious symptoms.
7. Pregnancy-Related Bleeding
Unexpected bleeding may sometimes be associated with early pregnancy, miscarriage or ectopic pregnancy.
If pregnancy is possible, a pregnancy test is an important first step.
If you might be pregnant and experience vaginal bleeding with abdominal pain, seek urgent medical assessment. Severe pain, shoulder-tip pain, dizziness or fainting may indicate an emergency.
When Should You Be Concerned About Spotting?
An isolated episode of light spotting does not necessarily indicate a serious problem. However, arrange a medical assessment if you experience:
- Repeated bleeding between periods
- Bleeding after sexual intercourse
- Persistent unexplained spotting
- Irregular bleeding accompanied by pelvic discomfort
- Changes in your usual menstrual pattern
- Bleeding that becomes more frequent or heavier
If bleeding occurs alongside persistent discomfort, explore the clinic's information on pelvic pain and gynaecological assessment.
Any vaginal bleeding after menopause should be assessed promptly, even when it happens only once or appears as a small amount of spotting.
Seek emergency care if bleeding is severe or accompanied by fainting, marked weakness or severe abdominal pain.
How Is Bleeding Between Periods Diagnosed?
Diagnosis begins with understanding your symptoms, medical history and menstrual pattern.
Medical History and Cycle Review
Your gynaecologist may ask about contraception, pregnancy possibility, medication, bleeding frequency and associated symptoms.
Pregnancy and Infection Testing
Depending on your circumstances, pregnancy testing and screening for infections may be recommended.
Pelvic Examination
An examination may help identify cervical changes, polyps, inflammation or other possible causes. It should be explained beforehand and performed with informed consent.
Pelvic Ultrasound
Ultrasound imaging may help assess the uterus, ovaries and endometrial lining, including possible fibroids or polyps.
Additional Investigations
Depending on symptoms and risk factors, further tests may include hysteroscopy, endometrial sampling or colposcopy.
Treatment Options for Bleeding Between Periods
Treatment depends on the underlying cause. For some women, reviewing hormonal contraception or managing hormonal changes may improve symptoms.
Infections may require medication, while polyps or fibroids may require monitoring, medical management or a procedure.
Women experiencing fibroid-related symptoms can explore available fibroid treatment options.
Not every patient requires surgery. Treatment should take into account symptoms, medical history, personal preferences and future pregnancy plans.

Frequently Asked Questions
Is spotting between periods normal?
Occasional spotting may occur because of ovulation or hormonal contraception. However, unexplained or recurring bleeding should be assessed.
Can stress cause bleeding between periods?
Stress can affect hormonal regulation and menstrual cycles. Nevertheless, bleeding should not automatically be attributed to stress without considering other causes.
Can fibroids cause spotting between periods?
Yes. Fibroids affecting the uterine cavity can contribute to abnormal bleeding. Ultrasound imaging may help identify fibroids.
Should I worry about bleeding after sex?
Bleeding after sex can have several causes, including cervical ectropion, infections, polyps or cervical abnormalities. Medical assessment is recommended.
Can bleeding between periods indicate cancer?
Most cases are not caused by cancer. However, abnormal bleeding can occasionally be associated with cervical or endometrial cancer, making appropriate investigation important.
Do I need a gynaecologist for irregular bleeding?
A GP or specialist gynaecologist can assess irregular bleeding and recommend investigations. Specialist care may be helpful for persistent symptoms or when additional testing is required.
