It is important to get the Rhogam shot if you are a negative blood type and your significant other is a postive. Negatuve blood type is a recessive trait, therefore its highly likely your baby will have a postivie blood type. A negative blood type means your blood cells lack a protien coating.
If you get the shot within five days of starting your period or within five days of giving birth, you are protected immediately. Otherwise, you need to use a backup contraception method for the first week. You will need to return to your doctorâs office every 12 weeks for another injection. If 14 weeks or more have passed since your last shot, your doctor may require that you get a pregnancy test before giving you another shot. Advertisement.
