Blood Groups

No. The problem is if YOU are RH-negative and the baby is RH-Positive, you can develop antibodies to the baby and attack it. It is worse for the second pregnancy with an RH-positive baby.

O-negative is actually a universal blood donor, with a lack of antigens.

There are many other things that can potentially raise risk of miscarriages. The best think is to talk to a fertility specialist.

The doctor should help you. Talk to your gyn and ask if there is a test that you could have done to help you out. Ask if you have an Rh factor that would need to be addressed.

I don't think that your blood type has anything to do with your miscarriages, but the doctors should know this for you.

Good luck!

Jeanie W is correct. Carrie, Lisa and Jo all have some of their facts incorrect. It's not true that anyone can have a baby with type O blood. (for example, if mother is AB and father is AB phenotype or even AA phenotype). You can have type A blood and have the AO phenotype, so if one parent is AO and the other is OO, which is type O, then the child could be either AO or OO, that is, type A or O. Rh + means the blood cells do have a certain antigen. And there's only a concern if the mother is Rh negative. Guess no one paid attention in biology class...

Positive denotes antibodies. In other words your first child did not have the antibodies so steps were most likely taken to insure the safety of that child. Since both you and your new husband are positive that should not be an issue.

Ask your Dr. about that, but also, ask him for a Thrombophilia workup. There are clotting disorders that some women have that can cause miscarriages. If you have one of these, then taking a low dose blood thinner throughout pregnancy can help. Something to check into.

If you are truly A+ then it doesn't matter what your husband or daughter's blood type. You cannot be affected by Rh incompatibility if you are a + blood type. The only really accurate way to determine your blood type is a type and match from your primary care provider. You might check into any prenatal records you can find with your first daughter - they always check your blood type prenatally. If you can't find those, go have your doctor order the blood test and then you'll know for sure.

I would have your child's blood type rechecked. The only way a child can have O type blood is if both parents have O type blood. Both blood types A & B are dominant. so in your situation, your child should have type A blood.
You can google "what will my childs blood type be"

The issue is when you, the mother, are a negative RH and the father or a child is positive RH. I am RH neg and had to have Rhogam shots with my children (both positive RH).

I have A- blood.......All 3 of my children have O+. Anyone can have an O baby. anyone can receive O-. All of my children have to be tested so I can get the Rogam shot. If you are positive then you dont need the shot and there arnet any problems with the blood unless you do turn out to be negative.

Yes negative and positive blood does not mix
They should have given you a shot if you were negative and baby was positive.
I am assuming same if you were positive and baby was negative
You need to check with your obgyn about this
