I just got my blood results from the other blood tests and they stated that I am A- which means I will have to get a injection at 28 weeks and right before gaving birth to create antibodies for the baby against infection or something like that.
Does anyone else have to do this?

Re: Does anyone have a A- blood type?

I'm AB- and DH is O+. The shot is for negative blood type mothers who may have a positive blood type baby. Check out the RhoGAM website.
Yep, it is the Rhogam shot. You have to have one if you are RH- and the father is Rh+.
I ended up w/ three shots w/ my son and I am not sure if I have to have more w/ this pregnancy.

If you are - .. and the your OH positive you have to have the Rhogam shot. Like others have stated it is the RH Factor. I had one after my miscarriage.. and I carry a card with me. This pregnancy i will have to have another shot after the baby is born.
At least they caught it early!! and now they know.. no big deal!!

I'm AB- and my husband is O-. I thought we (me) had to get the shot because we were BOTH negative?
So, am I understanding this now that no matter what, since I am a negative, I would need the shot regardless? And doesn't it have something to do wth blue baby syndrom? Not sure if that's what it is actually called, my mo just was saying something about it...
From what I understand, if you and your H are both negative, then the baby will be negative, so there is no danger or need for a shot. The danger comes if the baby is positive and the mother negative, and for that to happen the father would have to be positive. But, you know, I'm not a Dr, so I could be wrong about that.
ETA: Assuming H is the father of the baby. (After reading a pp, I thought I should add that.)
This! well put.
It's actually the other way around. If baby's + blood gets into Mom's - blood, mom will start to build antibodies against the + blood. This is only a problem for the next pregnancy, there will be enough antibodies in mom's blood to attack baby, which can cause serious problems, including m/c. Weird how the body works!
