Patient's question:

Detailed medical condition and consultation purpose: Post-missed medication abortion followed by Dilation and Curettage (D&C), why there is no bleeding after the D&C
Duration and course of the current illness:

Doctor's answer:

The number of days of bleeding mainly depends on individual circumstances, but generally, after an abortion, there will be a bleeding period of 7-14 days, and the amount of bleeding will not exceed the normal menstrual flow. If there is still no bleeding after observing for a few days, it should be considered whether there is a possibility of intrauterine inflammation and adhesion, and further examination is needed.
