"Missed miscarriage — You have no cramps or bleeding. But ultrasound shows an embryo without a heartbeat or an empty pregnancy sac without an embryo. Usually the tissue passes on its own, but you may need treatment.
Treatments for miscarriage include medicines or procedures that are very similar to those used for abortion."
