Can passing a piece of placenta one week after delivery affect my milk supply?
Sometimes a piece of placenta (fragment) remains in the uterus after delivery (retained). The fragment may continue to produce a hormone (progesterone) that makes the body behave as if it were still pregnant and keeps it from making milk. In order for the milk to come in, the fragment must be removed, either by the uterus expelling it or by surgery. Having a retained placental fragment may result in the milk coming in late or in the mother never having enough milk.
