Brown Bleeding During Pregnancy: What to Know

Brown discharge may appear when blood takes longer to leave the uterus or vagina and becomes darker as it changes colour. A small amount can occur after sex, a vaginal examination, or irritation of the cervix, which has more blood flow during pregnancy. Bleeding can also be linked with problems that need assessment, so colour alone cannot identify the cause.

The details matter: note whether the blood is only seen when wiping or is enough to need a pad, whether it is becoming brighter or heavier, and whether cramps or pain are present. In early pregnancy, bleeding may happen around the time an embryo attaches, but bleeding can also occur with an early pregnancy loss or an ectopic pregnancy. Later in pregnancy, bleeding has different possible causes and should be assessed by the maternity team.

Infection of the cervix, including Chlamydia, can cause bleeding or discharge. Cervical growths such as polyps may bleed after contact. Conditions such as uterine fibroids can also contribute to bleeding, although they do not explain every episode. These possibilities do not mean that a serious condition is present; an examination and, when needed, ultrasound or other tests help clarify what is happening.

Contact your obstetrician, midwife, or pregnancy assessment service and describe the colour, amount, timing, and any pain. Use a pad rather than a tampon so you can observe the bleeding, and avoid putting anything in the vagina until a clinician advises you. Keep track of clots, tissue, dizziness, fever, or a change in fetal movement if you are far enough along to notice a usual pattern.

Do not stop prescribed medicines or start treatment for the bleeding without medical advice. The clinician may ask about your pregnancy dates, blood group, previous pregnancies, recent sex or examinations, and symptoms of infection. Assessment may include checking your vital signs, examining the cervix, testing urine or vaginal samples, and arranging an ultrasound according to the stage of pregnancy.

Seek emergency care now for heavy or rapidly increasing bleeding, severe or one-sided abdominal pain, shoulder-tip pain, fainting, marked weakness, or severe dizziness. These symptoms can signal significant blood loss or an ectopic pregnancy, which requires prompt treatment. Go urgently as well if you have fever, feel very unwell, or notice reduced fetal movement after you have established a regular movement pattern.

Even light brown spotting deserves same-day advice if it keeps recurring, follows pain, or occurs later in pregnancy. Take your maternity notes and a list of medicines if you attend a hospital. If you are unsure whether the bleeding is urgent, call your local emergency service or maternity unit for immediate guidance.

Useful questions include: What are the likely causes at this stage of pregnancy? Do I need an examination, blood tests, or an ultrasound? Which symptoms should send me straight to emergency care? Should I change sexual activity, exercise, or medicines while the bleeding is being assessed? When should I contact you again if it stops but returns?
