After having an abortion, if there is no bleeding 5 days later, is it considered clean?

Patient's question:

No

Doctor's answer:

Currently, based on your description, it cannot be ruled out that it is caused by uterine contractions or that your period has started. It is recommended that you go directly to the hospital for a color Doppler ultrasound to check the thickness of the endometrium, which will help determine if your period has started.
