For women who deliver in normal labor, the low amount of malodorous fluid 5 days after delivery is generally considered to be a physiological manifestation caused by a particularly fast recovery of uterine contractions, because after delivery in normal labor, the uterine contractions are often better. If a woman in normal labor and breastfeeding, this can stimulate the uterus to contract quickly, so the amount of malodorous fluid will be significantly reduced by 5 days after delivery, and the time to clean up malodorous fluid for these women is also relatively fast, probably about 20 days after delivery. However, in the case of women who terminate their pregnancy by cesarean section, because of the slow contraction of the uterus after delivery, the low amount of malodorous fluid 5 days after delivery should be considered as an abnormality due to the lack of contraction of the uterus and the accumulation of blood in the vagina or uterine cavity. Therefore, it is necessary to press the woman’s uterus by hand to see the exact location of the uterine fundus and, if necessary, to put on disposable gloves and check inside the woman’s vagina to see if there is any blood clot accumulation.
