What are the symptoms of infection after a tire puncture?

Patient's question:

I had a painless miscarriage on the 23rd, and it started bleeding the very next day. Now it's been five days with bloody discharge accompanied by coffee-ground-like material. Today, I sat for three hours and noticed dark-colored, bloody. I want to ask if this is normal or if I might have been infected. I took three days of anti-inflammatory anesthesia for the surgery. Currently, I'm taking anti-inflammatory medication. What kind of anti-inflammatory medication would be suitable for me?

Doctor's answer:

Post-abortion Precautions
1. Rest for 2 weeks. Due to the looser cervix after abortion, there is a risk of retrograde infection. Strictly avoid baths and sexual activity for one month.
2. Take the prescribed antibiotics and medications as directed by your doctor to promote uterine contraction, such as motherwort and cephalosporin (if no allergy history).
3. Pay attention to dietary balance: Eat eggs, milk, fish, poultry, and meat while also consuming plenty of vegetables and fruits. Avoid cold foods.
MRI examination is required for 2 weeks to confirm uterine recovery.
