Is it normal to have bloody postpartum milk for more than a week with a foul smell?

Generally, bloody malodour lasts for 3 days and has a bloody smell, but no odour. If the bloody malodour lasts longer and is accompanied by an abnormal odour, pathological factors such as weak contractions, intrauterine infection, placenta-fetal membrane residue, etc. should be considered. It is recommended to seek medical advice to further identify the cause and treat it promptly.
