What should you know about reason behind missed miscarriage?

A missed miscarriage usually occurs because an early pregnancy stopped developing, often after a chance chromosome problem that could not have been prevented. The body may not immediately pass the pregnancy tissue, so there can be few or no warning symptoms. It is not usually caused by exercise, sex, work or an everyday emotional experience.

Pregnancy symptoms can continue for a while because hormone levels do not fall at once. Some people notice no bleeding or pain and learn about the loss during an ultrasound. A scan may need repeating when the pregnancy is very early or the dates are uncertain. Your clinician will explain what the images and hormone results show, and you can ask for time to take in the information.

You may be offered expectant care, medicine to help the uterus pass the tissue, or a procedure to remove it. The choice can depend on bleeding, infection, scan findings, your medical history and what feels manageable. Discuss pain relief, follow-up, emotional support and what to expect at home. Medical care after a miscarriage is available even when the loss was found without symptoms. Information about [Medical Management of Miscarriage](/treatments/medical-gynaecology/medical-management-of-miscarriage/) and [Surgical Management of Miscarriage](/treatments/gynaecological-surgery/surgical-management-of-miscarriage/) can help you prepare.

Get urgent medical help for heavy bleeding, severe or one-sided pain, fainting, fever, chills, or feeling suddenly very unwell. These symptoms can indicate significant blood loss or infection. Use the emergency service if you feel unsafe waiting for a routine appointment.

Ask whether the diagnosis is definite, which option is suitable for you, how long bleeding may last, and which symptoms should trigger a call. You can also ask when follow-up is needed, whether testing is advised, and when it is medically reasonable to try for another pregnancy.
