Rhogam Shot During Pregnancy: Timing and Reasons - Expert Explanation

Question
Hi
I had a rhogam shot at like 2 week pregnancy. do I need to have it again? and if so why and when?
I am very confused. not sure why they gave it to me so early

Answer
You may have been given the shot early if you had any bleeding.  Any instance of bleeding means there is a possibility that your blood mingled with the baby's, exposing you to Rh factors and setting you up for Rh antibodies.  You will likely be given the shot again later in pregnancy and/or after the birth, since one shot does not provide permanent protection.
