The sudden increase in the amount of malodorous fluid 10 days after delivery is considered to be due to poor recovery of the uterus, residual placental tissue in the uterus, and the presence of malodorous fluid in the uterus for too long, which can cause intrauterine infection. If you are breastfeeding, the contraction of the uterus will be stimulated by breast milk, causing an increase in the amount of malodex. Under normal circumstances, the amount of nightmare decreases gradually after a week, but it lasts longer and takes six weeks to be completely clean. If there is a sudden increase in the amount of nightmare, you should go to the hospital for an ultrasound examination to determine if there is an intrauterine infection or intrauterine residue. If you have intrauterine infection, you should take oral medication such as metronidazole and amoxicillin. If the uterus is not contracting well, you need to take motherwort or biochemical pellets, and if necessary, you can also use drugs such as uterine shrinkage.
