You will be given an injection of Rhogam around week 28 of pregnancy if the Rh test is negative.
What is rh-negative?
Red blood cells have a protein called rh factor on their surface. You are Rh positive if the protein is present in your blood. You are Rh negative if the protein is absent from your blood. You might see "+" or "-" after your blood type, which stands for Rh positive or Rh negative.
The frequency of Rh positive is substantially higher than Rh negative. Being Rh negative is not a disease, and it typically has no impact on your health. However, it might impact pregnancy. If you are Rh negative and your unborn child is Rh positive, your pregnancy requires special attention. It's referred to as Rh incompatibility. The Rh factor can be passed on to a child from either parent.
