To reduce this risk, a drug called RhoGAM should be given to Rh-negative pregnant women at 28 weeks of pregnancy and immediately after birth. This medicine prevents the mother’s body from recognizing Rh-positive cells in the Rh-positive baby. These injections make Rh-positive pregnancies safe for Rh-negative women. If you have Rh-negative blood, it is very important to tell your doctor about any bleeding during your pregnancy, while reminding him or her that you are Rh-negative. Depending on your situation, RhoGAM injections may be recommended if necessary.
