In a nutshell, my blood type is O-, meaning my Rh factor is negative. My blood does not contain a certain protein on my red blood cells indicated by the + or - behind the blood type. About 85% of people HAVE this protien. Justin is O+. When a woman who is Rh negative has a child with a blood type that is Rh positive (about 50% chance if the father is positive), then there is a chance that the mothers body could treat the baby as a poison, and produce toxins to fight it off.
Dr. Przybysz told me it usually doesn't have a negative impact on a first pregnancy because it's so rare that the baby's blood and the mother's blood will mix prior to delivery. However, the mother's body remembers and recognizes the protien in subsequent pregnancies and will make it's best effort to fight it off.
Fortunately, medical advances are such that this is no longer a big deal. There are two shots that I will have to get in order to prevent any potential negative reaction to a Rh+ baby. One will be at 28 weeks and one will be within 72 hours of delivery. I will have to have the shots with any other future pregnancies.

So, that's what I've been wanting to talk about! Anyone else have experience with this?
