i am 0- and my dh is +ve, both my children were born +ve. I was given the Anti-d injections when pregs with both children and both children where checked at birth for thier blood types, and i'm pretty sure i recieved this injection again after thier birth. These injections are blood products, therefore come from blood donors. (last i heard anyway). I am not an expert on these things but to give a bit of history of my family. My grandmother was a -ve and had 2 +ve babies - all was fine. My mum was born and required an urgent blood transfusion (she was a blue baby) as a result of my grandmothers antibodies killing off the 'foreign' antibodies in my mothers blood. (Now not trying to scare anyone)However when her next baby was born, the doctors said he would be fine but they waited to long to give the transfusion, and subsequently my uncle was born brain damaged through a lack of oxygen in his system. If they had these anit-d injections then i'm sure none of this would've happened. So alot has changed in 50years, and having this background knowledge i didn't hesitate to have the injections done. I would talk to your doctor, there are pamplets on this and alot of info on the net. good luck
