What should you know about on and off spotting 6 weeks pregnant?

Light spotting may occur when the cervix is more sensitive, including after sex or an examination. Other possibilities include infection, a pregnancy that is not developing as expected, or an ectopic pregnancy. The amount and colour of blood do not reliably identify the cause.

A clinician may ask about pain, bleeding, dizziness, dates, and previous pregnancies, then arrange an examination, blood tests, or an ultrasound. Bleeding between periods is a useful symptom page for general background, but bleeding during pregnancy should be assessed in its pregnancy context.

Contact your maternity service, early-pregnancy unit, or doctor for advice, especially if spotting continues or returns. Note when it happens, whether it follows sex, how much blood you see, and whether cramps or other symptoms accompany it. Use a pad rather than a tampon so the amount is easier to observe.

Do not self-diagnose from online causes. Conditions such as Chlamydia or cervical dysplasia can cause bleeding outside pregnancy, while cervical cancer, womb cancer, endometrial polyps, and uterine fibroids are other causes clinicians may consider in the appropriate setting; their presence is not established by spotting alone.

Seek emergency care for heavy bleeding, severe or one-sided abdominal pain, shoulder-tip pain, fainting, marked dizziness, weakness, fever, or feeling very unwell. These red flags can occur with ectopic pregnancy, significant blood loss, infection, or another urgent problem and should not wait for a routine appointment.

Ask whether you need an early-pregnancy assessment, what tests will confirm the pregnancy location and development, which symptoms should trigger emergency care, and how to contact the team outside normal clinic hours.
