Opposite Blood Types

I'm new to all this & just newly pregnant (4 weeks); I just wanted to know if you & DH have opposite blood types (-, +) at what point do you need to go in & have that injection?

I know my SIL had to have it, but she didn't find out until after she had a miscarriage the first time around.

Thanks.

Re: Opposite Blood Types

I think it's 32 weeks. It has nothing to do with DH, it's just your blood type that matters ,if you are RH -

Re: Opposite Blood Types

Oh okay, I thought it had to do with father & mother having opposite types. Thanks for the clarification

Re: Opposite Blood Types

I am O- and DH is A + so I had to have th Rhogan shot at 28 weeks. I have to have another one right after delivery.

Yup, I'm O- and DH is O+ they take care of it around week 30-32.

Re: Opposite Blood Types

Wow, I never knew this. I don't even know my blood type or DH's (I hope to learn mine from my blood testing the other day, and he says he knows his!)

I never knew this. Thanks!

Re: Opposite Blood Types

This is from CONSUMER HEALTH INTERACTIVE:

"If you're Rh negative and your baby's Rh positive, you have Rh incompatibility. As soon as your body comes into contact with the Rh protein -- a substance it's never seen before -- it begins making antibodies against it. For this reason, it may later mistake a fetus who's Rh positive for an unwelcome invader and develop an immune reaction that actually attacks it If you're Rh negative and your partner is Rh positive, there's a chance that your child will be positive, making incompatibility a concern. If you're Rh positive, it really doesn't matter if your child is negative or positive. If you're Rh positive, your body is already familiar with the Rh protein, and so the baby's Rh status will not be an issue. And if both you and your partner are negative, you don't have to worry about Rh incompatibility because your child will be negative, too."

"Rh incompatibility isn't usually a problem during your first pregnancy because blood from a developing fetus doesn't mingle with your own until the time of delivery. The immune system of an Rh negative mom has to be exposed to Rh positive blood one or more times before it can develop a response that is strong enough to harm the baby. But during labor and delivery, you will probably be exposed to some of your child's blood. If you're Rh incompatible, your body will start making antibodies against this "foreign" protein."
