The short answer
A missed miscarriage is when a pregnancy stops developing but there is no bleeding or pain, so it is only discovered on ultrasound, for example when no heartbeat is seen or the sac stops growing. It is not caused by anything you did. Your doctor will explain options, which may include waiting, medication or a procedure.
Regular early scans are how missed miscarriages are found. If it happens, we will talk through options and emotional support in English. See bleeding in early pregnancy.
