Old Blood Spotting During Pregnancy: What to Know

Old blood spotting during pregnancy often looks brown or rust-coloured, but any bleeding in pregnancy should be discussed with a maternity clinician because the cause depends on the stage of pregnancy and accompanying symptoms. Brown discharge can mean blood has taken longer to leave the vagina. Colour alone cannot show whether the bleeding is harmless or needs treatment.

Light spotting may follow irritation of the cervix, including after sex or an examination, because pregnancy can make cervical tissue more sensitive. Bleeding can also occur with changes in the cervix or with an infection. Chlamydia can present with bleeding, sometimes alongside pelvic discomfort, pain during sex, unusual discharge, or burning when passing urine. A pregnancy-related cause, such as a problem with the pregnancy or placenta, also needs to be considered according to how far the pregnancy has progressed.

The amount, colour, timing, and pattern matter, but they do not provide a diagnosis by themselves. Note whether the spotting is increasing, whether clots or tissue are present, and whether you have pain, dizziness, fever, or fluid leakage. A clinician may ask about your pregnancy dates, blood group, previous pregnancies, recent sex or examinations, and any medicines. Assessment can include an examination, ultrasound, urine testing, or blood tests when appropriate.

Contact your obstetrician, midwife, maternity unit, or an urgent medical service for advice, even if the spotting is brown and light. Use a pad rather than a tampon so you can observe the amount, and record when it began and whether it changes. Do not put anything into the vagina until a clinician has advised you, particularly if bleeding is continuing.

Keep your pregnancy details and medication list available when you call. If you know your blood group, mention it. Avoid taking a new medicine for pain or bleeding without checking that it is suitable in pregnancy. Follow the clinician's instructions about examination, monitoring, or attending a maternity assessment service.

Seek urgent medical help if bleeding becomes heavy, bright red, or rapidly increases; if you pass clots or tissue; or if you develop severe or one-sided abdominal pain, shoulder-tip pain, fainting, marked dizziness, fever, or feeling very unwell. Fluid leaking from the vagina, regular tightening, or reduced baby movements later in pregnancy also needs prompt assessment.

Do not wait for spotting to turn red before seeking help. Early pregnancy bleeding with pain or faintness can require immediate assessment, while bleeding later in pregnancy may need urgent review even without pain. If you cannot reach your maternity team, attend the nearest emergency service or call local emergency services.

Ask what might be causing the spotting at your current stage of pregnancy, whether you need an examination or ultrasound, and which symptoms should prompt an immediate return. You can also ask whether sex, exercise, or work activities should be changed while the bleeding is being assessed.
