Yes... When an Rh- mother carries a Rh+ fetus, some of the feral erythrocytes may cross the placental barriers into the maternal circulation, inducing her to synthesize anti-Rh antibodies. Because this occurs mainly during the separation of the placenta at delivery, a first Rh+ pregnancy rarely offers any danger to the fetus since delivery occurs before the antibodies are made by the mother. In future pregnancies, however, these antibodies will already be present in the mother and can cross the placenta to attack and hemolyze the erythrocytes or an Rh+ fetus. This condition, which can cause an anemia severe enough to result in death of the fetus in utero or of the newborn, is called hemolytic disease of the newborn. The risk increases with each subsequent Rh+ pregnancy as the mother becomes ingreasingly sensitized. This is prevented by giving the Rh- mother gamma globulin against Rh+ erythrocytes within 72 hours of delivering an Rh+ infant. These antibodies bind to the antigenic sites on any Rh+ erythrocytes that might have entered the mother's blood during delivery and prevent them from inducing antibody synthesis by the mother. The administered antibodies are eventually catabolized.

That would depend on the Father's blood type. The problem arises when the Mother's blood group is negative and her partner's positive. If the baby's blood group is positive, then the mother's body may form anti-bodies to the baby's blood, generally only effecting second and subsequent pregnancies. But that does include miscarriages and abortions.
Some hospitals do give the shot to any negetive mothers who give birth/miscarry and others do not.

If you are RH negative and you don't know the fathers blood type, then you should have had the shot (rhogam) after a miscarriage, to keep from becoming RH sensitive. And when pregnant at 28 wks you will be given a shot. If the father is also RH negative then you don't have to have the shot at all.

Your doctor should have told you this during a visit. Definitely ask them about it. There's always a chance that it won't affect the baby (depends on the father's Rh factor).
Basically, if the Rh factors don't match, your immune system views the baby as a foreign body and starts attacking it, causing the miscarriage. The shot is a preventative measure.

If you have rH negative blood and are carrying an rH positive child you can have a miscarriage ... but there is a 'shot' (it may actually be a series of shots) that can 'fix this' so you can have your baby. If you are rH negative, and the father is rH positive, the chances are 50% or better that your baby is rH positive, so TALK TO YOUR DOCTOR before you try to get pregnant again.

yes, it's completely true. Reason why is becuase your body thinks that the baby is bad and your immune system fights it off like a cold or a flu. When you get pregnant and take your first blood test, make sure you ask the doctor to do a RH Negitive test. I believe that you have to get a shot in your second or third trimester which helps your body from not killing the baby.

I have A- blood type and when I miscarried I had to go in and get a Rhogam shot right then. I also know that you have to get these shots when you are pregnant I believe at 7 months and then again after you deliver your baby.

Yes.
Lots of truth. The Rh factor has nothing to do with monkeys, though. It is a human blood factor put into your system if your previous pregnancy was with a man who has a positive blood type and the baby had a positive blood type.
You must be tested for Rh factor antibodies in your blood, which would develop after carrying a baby with positive blood. If you have no Rh antibodies, you won't need any shots. If you do have Rh antibodies, I have no idea what they will do for you, but it is in your best interest to go and find out.

Total truth.
My blood type is B- and my husband's is A+. So when I'm 28 weeks I have to get a shot to protect me and my baby just in case our blood mixes. I also have to get another shot when I give birth. Without the shot my body will develop anti-bodies against my NEXT pregnancy because it is a foreign object and will end up in miscarriage.

yes it is true. If you are Rh- and they Baby is RH+ you are at risk for miscarriage again. I think you get the shot at 28 weeks and shortly after birth. But you want to be Rh+ and the baby needs to be Rh+
