Postpartum for 2 months, lochia still occurs intermittently, what is the reason?

Patient's question:

No

Doctor's answer:

The lochia this period should be very little, with a very light color, milky white or milky yellow, and no unpleasant odor. If it appears dark red or the amount increases, or is accompanied by abdominal pain or other physical discomfort, consider the presence of inflammation, such as uterine cavity infection.
