After the postpartum check-up at 42 days, why is there still bloody lochia?

Patient's question:

No

Doctor's answer:

It is recommended to promptly visit the hospital for a follow-up check-up to assess the recovery of the uterus, determine if there are any possible retained intrauterine residues, and consider undergoing uterine curettage if necessary. Additionally, during breastfeeding, the indiscriminate use of medication is generally not advised. It is recommended to arrange things reasonably.
