It takes about 4-6 weeks for the dew to flow after the birth of a baby, and most women will have clean dew in about 1 month after delivery, which is in stages, and the color of the dew is different in different stages. In the 3-4 days after delivery, it is bloody, containing a lot of blood, and it is bright red in color, and sometimes you can see small blood clots, because the uterus is contracting rapidly and expelling the necrotic meconium and red blood cells. In the 5-10 days after delivery, you will have plasma nightmare, which contains more mucus, and the nightmare will gradually turn white until it is completely clean. The duration of the flow of nightmare is obviously related to the contraction of the uterus. The contraction of the uterus is good and the nightmare can end within a normal time, while the contraction is not good and the nightmare will increase and take longer.
