When can a missed miscarriage happen?

It means an embryo or fetus has stopped developing but pregnancy tissue remains in the uterus, sometimes without bleeding or cramping. The pregnancy may therefore appear to continue until an ultrasound or another clinical assessment raises concern.

Pregnancy symptoms such as nausea or breast tenderness can continue, lessen or fluctuate, and those changes alone cannot diagnose a miscarriage. Some people notice no change at all before a routine scan.

Ultrasound findings are interpreted alongside pregnancy dates and prior results. If dates are uncertain or a scan is inconclusive, the clinician may arrange a repeat scan or other checks before confirming the diagnosis. This avoids making a decision from a single ambiguous finding.

Your clinician will discuss waiting for tissue to pass naturally, using prescribed medicine, or having a procedure. The suitable choices depend on symptoms, scan findings, medical history, infection or bleeding concerns, and what feels manageable to you.

Ask for written information, pain-relief guidance, an after-hours contact and a follow-up plan. You may want a trusted person present for discussions because shock and grief can make details difficult to absorb. Miscarriage is not caused by routine movement, work or a moment of emotional stress.

Contact a pregnancy assessment service promptly for vaginal bleeding, persistent or worsening cramps, fever, unpleasant-smelling discharge, or feeling unwell. Bleeding or pain in pregnancy has several possible causes, so symptoms need assessment rather than assumptions about a missed miscarriage.

Call emergency services for heavy bleeding, fainting, collapse, confusion, severe one-sided abdominal pain, shoulder-tip pain or breathing difficulty. These signs can reflect major blood loss or an ectopic pregnancy and require immediate evaluation.

Ask what confirmed the diagnosis, whether another scan is needed, and what each management choice involves. Clarify expected bleeding and pain, reasons to change approach, how completion will be checked, and where emotional or bereavement support is available.
