It depends on the blood type of the father. If he is also RH negative then no, you don't need to get the injections because there is no chance that your baby will be RH positive (which is when the danger occurs). If the father is RH positive then there is a chance that baby is also positive, and then you need to recieve the shot after any sensitizing event. A fall, a placental abruption, or birth for example. The 28 week shot is not strictly NECESSARY, it's more like "just in case" you had a sensitizing event, even though you would have to have had the event less than 72 hours prior to the shot. It really is totally pointless unless you did have an event and have an RH positive partner.
