I want to know what is incomplete miscarriage

Patient's question:

Patient: Female, 19 years old, in good health. Current condition: 1. At 10 a.m. today, while doing laundry, I suddenly noticed skin breakdown in the vaginal area.
Past treatment history and effectiveness: 1. I underwent a thorough examination at the nearest hospital. 2. The doctor diagnosed it as a molar pregnancy and recommended an abortion followed by uterine clearance. 3. My husband and I did not believe this, so we went to the city for another examination. 4. The doctor said it was not a molar pregnancy but rather incomplete miscarriage, suggesting uterine clearance.
What kind of help is needed: 1. What is incomplete miscarriage? 2. Can I avoid uterine clearance? 3. Will uterine clearance affect future fertility?

Doctor's answer:

Post-abortion Precautions
1. Rest in bed for the first three days if possible. It is recommended to rest for 1-2 weeks after an abortion, as this may shorten the duration of vaginal bleeding. Avoid strenuous physical labor and exercise for at least half a month, and avoid working in cold water to prevent a weakened immune system from leading to other illnesses.
2. Pay attention to maintaining personal hygiene at all times, as poor hygiene can increase the risk of infection. Abstain from sexual activity for at least one month after an abortion. During the healing period, change sanitary pads frequently. Avoid soaking in baths for half a month and opt for showers instead.
3. Ensure proper nutrition by consuming foods rich in protein and vitamins, such as fresh fruits and vegetables, lean meat, fresh fish, eggs, dairy products, or soy products.
