Understanding the possible causes can help you decide when it may be appropriate to seek medical advice.

Key takeaways

Spotting between periods can have several possible causes.
Hormonal changes and contraception are common reasons for breakthrough bleeding.
Persistent, recurrent or unexplained bleeding should be assessed.
Changes to your usual menstrual pattern may warrant medical advice.
A medical assessment can help identify the cause and determine whether further investigation is needed.

What is spotting between periods?

Spotting refers to light vaginal bleeding that occurs outside of your normal menstrual period.

It is typically lighter than a period and may appear as pink, red or brown staining.

Some women experience spotting only once, while others may notice it at certain points during their cycle.

Although occasional spotting can occur for benign reasons, any change in your usual bleeding pattern is worth paying attention to.

What causes spotting between periods?

There are several potential causes of bleeding between periods.

Common causes include:

Hormonal fluctuations
Ovulation
Hormonal contraception
Perimenopause
Pregnancy-related changes
Cervical changes
Infections
Certain gynaecological conditions

The cause often depends on factors such as age, medical history, contraception use and whether other symptoms are present.

Spotting around ovulation

Some women experience light spotting around the middle of their menstrual cycle when ovulation occurs.

Ovulation happens when an egg is released from the ovary.

Hormonal changes at this stage of the cycle can occasionally cause a small amount of bleeding.

Ovulation spotting is usually light and short-lived.

Contraception and breakthrough bleeding

Hormonal contraception is one of the most common causes of spotting between periods.

This may occur with:

Combined contraceptive pills
Progesterone-only pills
Contraceptive implants
Hormonal coils
Contraceptive injections

Breakthrough bleeding is often more common when starting a new contraceptive method or during the first few months of use.

If bleeding persists or becomes troublesome, it is worth discussing with a healthcare professional.

Spotting during perimenopause

Hormonal changes during perimenopause can affect the menstrual cycle in different ways.

Some women notice:

Irregular periods
Lighter periods
Heavier periods
Spotting between periods

While cycle changes can be common during this stage of life, unexpected bleeding should still be assessed, particularly if it is persistent or worsening.

Can spotting be related to pregnancy?

Light bleeding can sometimes occur in early pregnancy.

However, bleeding during pregnancy can have a number of possible causes.

Anyone who is pregnant, or thinks they may be pregnant, and experiences unexpected bleeding should seek medical advice.

When should spotting be checked?

While occasional spotting may not always indicate a serious problem, some situations should be assessed by a healthcare professional.

It is advisable to seek medical advice if:

Spotting happens repeatedly
Bleeding becomes heavier
Your menstrual pattern changes significantly
Spotting occurs after sex
You experience pelvic pain
Bleeding occurs after menopause
You have any concerns about unusual bleeding

Persistent symptoms should not be ignored, even if they seem mild.

Conditions that can cause abnormal bleeding

Bleeding between periods can sometimes be associated with underlying gynaecological conditions.

These may include:

Fibroids
Polyps
Endometriosis
Adenomyosis
Polycystic ovary syndrome (PCOS)
Cervical abnormalities
Infections

Many of these conditions are manageable once identified, which is why assessment can be important.

What happens during a medical assessment?

If you seek advice about spotting between periods, a clinician will usually ask about:

Your menstrual cycle
The timing and pattern of bleeding
Current medications
Contraception use
Pregnancy risk
Other symptoms

Depending on your symptoms, further assessment may be recommended.

This could include blood tests, hormone testing or referral for additional investigations where clinically appropriate.

Why menstrual changes should not be ignored

Every woman has a slightly different menstrual pattern.

Because of this, it is important to be aware of what is normal for you.

New, persistent or unexplained bleeding should not automatically be assumed to be hormonal or stress-related without proper assessment.

Seeking medical advice can help identify the cause, provide reassurance and ensure that any underlying issues are addressed promptly.

Final points

Spotting between periods is common and often has a straightforward explanation.

Hormonal fluctuations, ovulation, contraception and perimenopause are among the most common causes.

However, bleeding that is persistent, recurrent or unusual for you should be assessed by a healthcare professional.

If you have noticed changes in your menstrual cycle or are concerned about unexpected bleeding, seeking medical advice can help identify the cause and determine whether any further investigation is needed.
