Normally, postpartum malodour will be completely drained within 6 weeks. If the mother is in good health after delivery, it is normal to have bloody nightmare within one week after delivery. If there is still bloody nightmare for more than a week, it means that the body is slow to recover and medicines such as motherwort can be used to promote the recovery of the uterus. After the bloody nightmare, the plasma nightmare usually lasts 1-2 weeks, and finally the white nightmare lasts about 3 weeks, depending on the individual. Therefore, if the mother recovers quickly, the nightmare may disappear completely within a month after delivery; however, if the nightmare is not cleared 42 days after delivery and there is still bleeding, it is recommended to go to the hospital for a review in time. After delivery, you should pay attention to appropriate activities on the floor, let your baby suckle more, and take drugs to promote uterine recovery under the guidance of your doctor if necessary, all of which are beneficial to the discharge of malodex.
