Black spotting in early pregnancy: what to do

Some light spotting settles without affecting the pregnancy, while bleeding can also be associated with early pregnancy loss or a pregnancy developing outside the uterus. The accompanying symptoms determine how urgently you need assessment.

A small amount of blood can turn brown or nearly black while it remains in the vagina. It may follow cervical contact during sex, occur around an early change in the pregnancy, or come from cervical inflammation or infection.

A miscarriage can present with vaginal bleeding and cramping. An ectopic pregnancy can present with bleeding plus pelvic or abdominal pain, often more prominent on one side. Neither condition can be confirmed or excluded from blood colour alone.

Call an early-pregnancy service or obstetric clinician, even if the spotting is light, and give the first day of your last period, pregnancy-test timing, bleeding amount, and whether the flow or colour is changing. Include any pain, nausea, faintness, fever, or unusual discharge.

Wear a pad to observe the amount and avoid tampons or vaginal intercourse until you have received advice. A clinician may recommend examination, ultrasound, or repeat pregnancy-hormone blood tests, depending on pregnancy timing and symptoms.

Go for emergency assessment if you develop severe or increasing abdominal or pelvic pain, one-sided pain, shoulder-tip pain, fainting, substantial dizziness, weakness, or heavy bleeding. These signs can occur with significant blood loss or an ectopic pregnancy.

Seek urgent care as well for fever, chills, foul-smelling discharge, or feeling acutely unwell. Ask someone else to drive or call emergency services when dizziness, fainting, or severe pain makes travel unsafe.

Ask whether the pregnancy location has been confirmed, what the scan can show at this stage, whether blood tests need repeating, and exactly which changes should bring you back. Tell the clinician about earlier ectopic pregnancy, miscarriage, fertility treatment, pelvic infection, or tubal surgery.
