Well, it looks like I have to get the RhoGAM shot. ARGH. Greg went in and had his blood type tested, and it turns out he is O+. Since I am O-, that means the shot will be necessary for me. Darn, I was really hoping that he would come up with an RH-negative blood.
I guess if I were to look on the plus side, at least I could donate blood for him should he ever need it, since O+ blood types can only receive O- and O+ type donations. He just couldn’t reciprocate since I can only receive O-. My immediate family is all O- though, so no worries there.
