Can a husband have a positive blood type and cause my body to reject my babys blood type?

Question

I had a miscarriage because my husbands blood type is positive and it caused my babys blood type to be positive and my body rejected the baby....why did my baby reject my body?

Answer 1

Yes, it's called rh factor incompatibility. Basically, your body thought that your developing baby was an invader, like a bacteria or a virus, because it's blood was too different from yours.

Before you get pregnant again, you need to see a doctor and find out if you can prevent this by getting some shots of a medicine called Rhogam.

Answer 2

Usually one of the first things they test for at the ob/gyn when you are pregnant is your Rh factor. You can take shots to not have the baby rejected (just so you know for future reference.)
From What to Expect when you are Expecting:
If a woman turns out Rh Positive, or both her and her husband are negative, there is no cause for concern. However, if she is Rh negative and her husband is Rh positive, she is a canidate for Rh incompatibility problems and her pregnancy must be kept under obstetrical surveillance....
... Trouble doesn't start brewing until the Rh factor enters the Rh negative mother's circulatory system during the delivery of abortion or miscarriage of a child who has inherited the Rh factor from his or her father. The mother's body, in a natural protective immune respones to the "foreign" substance, produces antibodies against it. The antibodies themselves are harmless- until she becomes pregnant with another Rh-positive baby. Then the antibodies cross the placenta and attack the fetal red blood cells, causing very mild (if maternal antibody levels are low) to very serious (if they are very high) anemia in the fetus. Only very rarely do these antibodies from the first pregnancies, in reaction to the fetal blood leaking back through the placenta into the mother's circulatory system.

I am sorry about your loss. I know I am just a stranger, and my words don't matter, but I hope everything is okay. I can't say I know what you're going through, because it has never happened to me, but I will be thinking about you, and your next pregnancy.

Answer 3

I'm assuming by your description that you are negative (and your husband is positive).

It should not affect the first pregnancy. If it did, a doctor needs to give you some answers. Maybe something else is wrong.

Normally you get a shot after the first pregnancy (or is it still while you are pregnant?) that enables you to have additional children with little incompatibility risk.

As an example. I am O+, Dad is O+, and my Mom is O-. Pregnancy was fine and I am fine. And she did get the shot.

Answer 4

you must have a negative blood type.
if caught in early pregnancy (or even before) there's medication you can take so your body doesn't reject the baby.

the reason your body rejected it is because the anti-bodies in your blood found foreign cells and started attacking it, your blood was obviously "stronger" because it successfully killed out the intruder. That's what our blood is supposed to do, it's one of it's primary functions. Your blood was trying to keep you healthy.

Answer 5

Because the baby was seen by a parasite or a virus so your blood attacked the baby.
