Chances of missed miscarriage at 8 weeks

In a missed miscarriage, development has stopped but bleeding or cramping may not have begun. Pregnancy symptoms can continue, fade or fluctuate in pregnancies with different outcomes, so their presence or absence cannot provide a reliable probability for one person.

Ultrasound assesses the pregnancy's location, size and development. Dates based on the last menstrual period can differ from actual development if ovulation occurred later than expected. When findings are too early or uncertain for a firm diagnosis, the clinician may recommend a repeat scan after an appropriate interval rather than drawing a conclusion from one image.

Blood tests may sometimes add context, but ultrasound findings and clinical assessment guide the diagnosis. A qualified clinician should explain whether the scan is definitive or still uncertain before treatment decisions are made.

Contact your maternity or early-pregnancy service if you have bleeding, pain, a sudden concern about symptoms or uncertainty about a scan result. Keep the scan report and clarify the follow-up date. If a missed miscarriage is confirmed, the available approaches may include waiting for the pregnancy tissue to pass, medication or a surgical procedure. The suitable choice depends on your symptoms, clinical findings, preferences and access to follow-up.

Seek urgent assessment for heavy bleeding, severe or one-sided abdominal pain, shoulder-tip pain, fainting, marked dizziness, fever, chills, foul-smelling discharge or feeling very unwell. Call emergency services for collapse, severe weakness or bleeding accompanied by faintness. These warning signs require evaluation for blood loss, infection or an ectopic pregnancy, regardless of any previous scan.

Ask whether the scan result is conclusive, how pregnancy dating was estimated, whether another scan is needed and whom to contact if symptoms change. After a confirmed loss, ask what each management option involves, how pain and bleeding will be managed, what follow-up confirms completion and where emotional support is available.
