Bleeding Between Periods: What Should You Tell Your Gynaecologist?

Tell your gynaecologist when the bleeding happened, how much there was, whether pregnancy is possible, and whether you have pain or bleeding after sex. Bring a list of medicines and contraception, plus any previous test results. Bleeding between periods has several possible causes; the pattern helps guide assessment but cannot diagnose the cause on its own. Even light spotting should be discussed rather than automatically blamed on a fibroid or a contraceptive. [1,2]

This guide is about preparing for an initial assessment, not choosing a fibroid procedure. Bleeding seen at the vagina may come from the vagina, cervix or uterus, and pregnancy-related bleeding needs a different pathway. [1,2]

First check whether you need urgent help

If you have recently missed a period, have unusual vaginal bleeding and have abdominal or pelvic pain, seek urgent medical assessment. An ectopic pregnancy is one possible cause and needs prompt evaluation. Do not wait for a routine appointment or for a home pregnancy test to become positive if you think pregnancy is possible and have concerning symptoms. [1,3]

Seek emergency care immediately for sudden, severe abdominal pain with marked dizziness or fainting. Shoulder-tip pain when pregnancy is possible also needs medical advice right away because it can be associated with internal bleeding. These symptoms do not prove an ectopic pregnancy, but they should not be managed by an online bleeding diary. [3]

Heavy bleeding can also require emergency care even when pregnancy is not suspected. ACOG advises emergency care for bleeding that requires changing pads or tampons every hour for more than two hours in a row together with symptoms such as chest pain, shortness of breath, lightheadedness or dizziness. Do not treat that threshold as a reason to wait if you are seriously unwell. Use emergency services where you are rather than waiting for a clinic message. [2]

Record the pattern in plain language

A calendar, private phone note or paper diary is enough. ACOG recommends noting the dates, length and amount of abnormal bleeding; a diary helps the clinician see a pattern that may be difficult to recall during an appointment. Do not delay arranging care to collect several weeks of entries. [2,4]

Useful details to bring include:

• Timing: the first day of your last usual period, your usual cycle pattern, and the dates the extra bleeding started and stopped.
• Amount: spotting only when wiping, staining underwear, or bleeding needing menstrual protection; note how often you changed protection and any flooding or clots.
• Relation to sex: say clearly if bleeding occurred during or after sex, even if it was only a small amount.
• Associated symptoms: pelvic or abdominal pain, pain during sex, unusual discharge, dizziness, breathlessness or feeling faint.
• Change over time: whether this is the first episode, whether it keeps recurring, and whether it has become heavier or more painful. [1,2]

Use your own description rather than trying to decide that the blood is definitely from the uterus. The clinician may need an examination to identify the source. Blood colour or a familiar point in the cycle is not enough to choose a treatment. [1,2]

Mention pregnancy, contraception and medicines early

Tell the clinician if pregnancy is possible, whether you have taken a pregnancy test, and when. Mention recent pregnancies and relevant procedures. Pregnancy-related causes, including miscarriage and ectopic pregnancy, must not be grouped with ordinary non-pregnancy bleeding. [2,3]

Bring the names of any contraceptive pills, injections, implants or intrauterine devices, and say when you started or changed them. Hormonal contraception can cause unscheduled bleeding, but that possibility should not replace assessment of an unexplained change. [1,2]

List prescribed medicines, over-the-counter products and supplements. In particular, tell the clinician about blood-thinning medicines, aspirin and hormone therapy. Do not independently stop a prescribed medicine or remove a contraceptive device because of this article; ask the prescribing clinician how to manage it safely. Your personal and family history, previous gynaecological problems and relevant surgery also help guide the assessment. [2]

Several causes can produce a similar symptom

Possible causes include hormonal contraception, polyps, fibroids and sexually transmitted infections such as chlamydia. Bleeding after sex may be associated with cervical surface changes, cervical polyps, vaginal dryness or infection. Changes in ovulation can also alter the bleeding pattern. [1,2]

Less commonly, unusual bleeding can be a sign of cancer. This is a reason to get checked, not a statement that spotting means cancer. Likewise, already having a fibroid does not establish that it caused this particular episode. The first question is what explains the bleeding, not which procedure to book. [1,2]

Bleeding after menopause is a separate concern, not a new menstrual period. If you have vaginal bleeding after menopause, arrange assessment even if it happened only once or was only a small amount. Tell the clinician about any hormone therapy. [2,6]

Tests are chosen to answer specific questions

The appointment usually starts with your symptoms and medical history. Depending on the situation, assessment may include a pregnancy test, a blood test, tests for sexually transmitted infections, and an examination of the vagina and cervix. Further investigation may involve ultrasound, colposcopy or hysteroscopy. Not everyone needs every test, and these procedures look at different areas. [1]

• Pregnancy testing helps determine whether a pregnancy-related pathway is needed.
• Blood tests, including a complete blood count when appropriate, can assess consequences such as anaemia; they do not by themselves identify the source of spotting.
• Examination and infection testing can investigate vaginal or cervical causes that a discussion about fibroids alone might miss.
• Ultrasound creates images of pelvic organs. Colposcopy examines the cervix in more detail. Hysteroscopy allows a clinician to look inside the uterine cavity. A sample of the uterine lining may be considered depending on the symptoms, age and risk factors. [1,2]

Guidelines must be read in context. NICE NG88 is a guideline for heavy menstrual bleeding, not a universal testing checklist for every isolated episode of spotting. In that population, persistent bleeding between periods can be a reason to offer hysteroscopy when the history suggests polyps, submucosal fibroids or endometrial pathology. It also advises considering an endometrial biopsy at hysteroscopy in people at high risk of endometrial pathology. This does not mean that everyone with spotting needs an immediate biopsy. [5]

Ask what each proposed investigation is intended to find, what it cannot exclude, and whether another test or referral would be needed if symptoms continue. This article does not confirm a particular test package, price or referral arrangement at BARUN. [1,2,5]

Leave with a follow-up plan, not just a test result

Treatment depends on the cause. An infection, a contraception-related problem, a polyp and a pregnancy complication do not have the same management. Some situations can be managed with medicines or an adjustment supervised by the clinician; others need further investigation, a procedure or referral. Neither HIFU nor another fibroid treatment is a general answer to unexplained bleeding. [1,2]

Before you leave, ask how and when results will be communicated, what to do if bleeding recurs, and which symptoms mean you should seek urgent care. If the bleeding stops before the appointment, still describe the episode and ask whether the planned assessment should proceed. Do not assume that stopping temporarily has identified the cause. [1,2]

Frequently asked questions

Should I wait for another cycle before asking about light spotting?

You can arrange an assessment now. NHS advice is to have bleeding between periods or after sex checked. Keep a record while waiting, but do not postpone urgent care to complete a diary. [1,4]

If I have fibroids, can I assume they explain the bleeding?

No. Fibroids are one possible cause, but pregnancy, contraception, infection, cervical changes and other conditions may need consideration. Explain what is new or different rather than relying only on an earlier scan result. [1,2]

Does an ultrasound replace looking at the cervix?

They answer different questions. An ultrasound images pelvic organs, while an examination assesses the vagina and cervix directly; some people need more detailed cervical assessment or investigation of the uterine cavity. Your symptoms and findings guide the choice. [1,2]
