the previous poster is incorrect.
I am rh- as well. And your blood type alone has nothing to do with 'killing the baby'. It is if your blood crosses PATHS with the baby's blood and you have antibodies in your system, your blood see's it (baby's blood) as a threat - and will kill off the healthy cells like an infection - in turn, causing you to miscarry.
This only can happen IF you bleed during pregnancy.
I had my first pregnancy to term, and had a rhogam shot at 28wks, and after birth. I also had to have a shot when I started bleeding in my first 2 miscarriages (to protect future pregnancies), I then had a 16wk miscarriage, and after I delivered him, I also had a rhogam shot.
I am 18wks along now and when I was 6wks I started bleeding, but I had antibodies already - meaning I didn't need the shot because it could have caused issues because basically doubled up on the antibody # in my system. So now I have to be monitored monthly to see that the levels either stay the same, or get lower, because if they get higher, that means danger for baby (possible anemia, blood transfusions in womb or after birth etc). And have to have the shot every 12wks so that everything in my system stays the same.
I'd do some reading up on it because there's lots of information on it.
My partner is also a+ so baby is bound to have a positive blood type. Basically the rhogam shot tricks your body into thinking the baby's blood is the same, if it ever crosses paths with yours.
Yes it is going to keep killing the baby. But they have shots now for that. I'm not sure how u go about getting them but they do make it so u can have one in ur situation
