How long does medical management of miscarriage take to work for missed miscarriage?

A missed miscarriage may have no immediate bleeding or pain, even though the pregnancy has stopped developing. The prescribed medicine makes the uterus contract and pass pregnancy tissue. Cramping and bleeding can be heavier than a period, with clots or tissue, then gradually ease. Some people need another dose or a different treatment if the uterus does not empty fully. A follow-up assessment, often involving symptoms, examination or a scan, confirms whether the process is complete. Emotional recovery rarely follows the same timetable as physical recovery, and mixed feelings are common. Your clinician can explain what to expect based on the medicine, pregnancy stage and your medical history.

Take the medicine exactly as prescribed and make sure you know what pain relief is suitable for you. Arrange access to sanitary pads, fluids, food and a trusted support person if possible. Follow instructions about monitoring bleeding and attending the follow-up check. Avoid inserting anything into the vagina or having sex for the period your clinician recommends. Write down when medicine was taken, how much you bleed, your temperature and any pain or dizziness. Contact your care team if bleeding or pain does not follow the plan they gave you.

Get emergency help for very heavy bleeding, fainting, severe or one-sided pain, severe dizziness, fever, chills, confusion, breathing difficulty or feeling acutely unwell. Seek prompt advice if pain is worsening rather than easing, bleeding has a strong unpleasant smell, or you cannot keep fluids down. If you know you have a negative blood group, ask your clinician whether any additional treatment is needed. Do not wait for routine follow-up when severe symptoms occur.

When should cramps and bleeding begin after I take the medicine? How will I know whether the miscarriage is complete? What should I do if bleeding is light, absent or continues longer than expected? What pain relief, follow-up test and emotional support are available to me?
