If you have a miscarriage while breastfeeding, you need to stop breastfeeding for about a week if medication was used in the miscarriage. If no medication was used, breastfeeding can continue. Miscarriage during breastfeeding may be spontaneous or induced, if it is a spontaneous miscarriage, there is no effect on breastfeeding. If the natural abortion is not complete, you need to carry out a purging operation. If you use anesthetic drugs, you need to wait for the drugs to metabolize before breastfeeding. If it is an abortion, the drug abortion needs oral mifepristone and misoprostol, and the surgical abortion needs injection of anesthesia drugs, which may enter the baby’s body through the breast milk and have an effect on the baby. Therefore, in the case of abortion, it is necessary to suspend breastfeeding and wait for the drugs to be metabolized before breastfeeding.
