Question: how soon after miscarriage do i need a rhogam shot?
Answer: How Soon After a Miscarriage Do I Need the RhoGAM Shot? If you are Rh negative, meaning that your blood does not contain the Rh factor protein, your doctor will probably recommend that you get an Rh immune globulin shot (such as RhoGAM) within 72 hours of the start of your bleeding.
