What should you know about a slow miscarriage?

“Slow miscarriage” is not a precise medical diagnosis. People may use it for bleeding that increases over time, cramps that come in waves, or a pregnancy loss where some tissue remains in the uterus. Bleeding in early pregnancy can also occur for other reasons, so symptoms alone cannot establish a miscarriage.

Assessment may include questions about symptoms, an examination, pregnancy hormone testing, and a [Transvaginal Ultrasound](/treatments/diagnostics-and-imaging/transvaginal-ultrasound/). The purpose is to clarify whether the pregnancy is developing, has ended, or whether tissue remains.

Contact your pregnancy-care team for advice. Use sanitary pads so you can observe bleeding, rest if you feel faint, and avoid inserting anything into the vagina until advised. If miscarriage is confirmed, options may include waiting for the tissue to pass, medicines, or a procedure. Your clinician can explain timing, follow-up, and what to expect with each approach.

Emotional reactions can be intense even when the physical symptoms seem limited. Support from a trusted person and a healthcare professional can help you manage both aspects of the experience.

Go to urgent care for heavy or rapidly increasing bleeding, severe or one-sided pain, fainting, shoulder-tip pain, fever, chills, or feeling seriously unwell. Seek prompt assessment for bleeding during pregnancy even when it is light, particularly if pain or dizziness is present.

Ask what tests are needed, whether the pregnancy location and development are clear, which management options suit your situation, how pain and bleeding will be managed, and when follow-up should occur.
