Bleeding regularly after periods: what to know

A clinician can clarify whether the blood comes from the vagina, cervix or uterus and choose tests from your history and examination. The cause may be related to hormone changes, contraception, infection, a cervical change, a polyp or a fibroid; these possibilities cannot be separated by timing alone.

Bleeding between periods can range from faint spotting to a flow needing menstrual protection. Blood appearing soon after an expected period may represent a longer bleed, while a clear gap followed by fresh blood is intermenstrual bleeding. Cervical inflammation, including that caused by chlamydia, can present with irregular bleeding. Endometrial polyps and uterine fibroids can also present with bleeding outside the expected period. Cervical dysplasia and cervical cancer may present with abnormal vaginal bleeding, but the symptom does not identify the cause.

Pregnancy remains relevant if conception is possible, even when bleeding resembles a period. Menopause changes the interpretation: any vaginal bleeding after periods have stopped because of menopause should be assessed promptly.

Arrange a routine appointment if this pattern recurs, persists or is new for you. Record the start and end of each period, bleeding between them, flow, clots, pelvic pain, discharge, bleeding after sex and any missed contraception. Take a home pregnancy test if pregnancy is possible. Do not stop prescribed hormones or contraception without discussing a suitable alternative.

An assessment may include a pregnancy test, infection testing, examination of the vagina and cervix, and review of cervical screening history. Depending on age, symptoms and findings, the clinician may discuss blood tests, pelvic ultrasound or sampling tissue from the womb lining.

Seek urgent medical help for heavy bleeding with fainting, marked dizziness, breathlessness, chest discomfort, severe or worsening pelvic pain, or feeling acutely unwell. Urgent assessment is also needed if pregnancy is possible and bleeding occurs with one-sided pain, shoulder-tip pain, weakness or collapse. Fever with pelvic pain or unpleasant-smelling discharge also warrants prompt care.

Ask which source of bleeding seems most likely, whether pregnancy and infection tests are appropriate, whether your medicines or contraception could affect the pattern, and whether you need an examination, ultrasound or womb-lining assessment. Confirm how to act if the bleeding becomes heavier while you wait.
