Having an injection of anti-d can prevent your system from making antibodies. It's important to prevent antibodies from being made, because once they're produced, they stay in your blood forever.

However, if you are not treated with anti-d, the immune response in your second pregnancy will be stronger than the first pregnancy and can cause rhesus disease in your baby. Your antibodies start to attack your baby's blood cells during pregnancy and can carry on attacking them for a few months after the birth (nhs choices 2013a).

If the anaemia becomes severe, it can lead to life-threatening problems for your baby, such as heart failure, fluid retention and swelling (nice 2008b). After shes born, your baby's liver won't be able to cope with the volume of blood cells that need breaking down.
