why does this worry you?

Hi Sunny - dont mean to be nosey but why is this a worry too you? if you dont mind me asking.

My husband and I have the same blood type and everything is fine with our baby. Just like the other women, I don't understand why you are worried. Now if you were Rh- then I would be worried about that shot that those women have to get. Other than that, I doubt you have anything to worry about.

Isn't having the same blood type a good thing, I would think there would be less chance of a problem?????


Donna - March 17

Thats what i thought, i dont really understand it though so i was just wondering why its a worrying thing for her.

Sunny, blood type is fine to be the same. Potential problems arise if say you are RH- and your husband +. (85% of people are RH+) If the above occurs, the baby most likele will be RH+ in an RH- mother's womb. Still not a problem since the embryo blood does not intermix with the mother's. Problem usually may occur with delivery, where the mother's and baby's blood is more likely to intermingle...... but to cut the long story short even if that is the case, it's treatable with much success today, so stop worrying, congratulations and good luck!

now i understand there is a shot for mothers who are rh - (atleast from what i have read recently) but what does the shot do exactly?


BBK - March 17

To Curious: There are several scenarios though, and the explanation is quite lengthy, but in a nutshell an injection of Rh immune-globulin prevents the mother's body from producing any potentially dangerous Rh antibodies that can cause serious complications in the newborn later on.

Sorry I pressed submit too soon. You can think of immune-globulin as a vaccine against rh antibody production. It's usually administered to first time mothers twice, once around 28 weeks and once after birth to prevent rh antibody production in future pregnancies. If antibodies have already formed, the pregnancy will be monitored so the levels don't become really high. In very rare (1%) cases a special series of transfusions is performed.

I asked my mom about this - she's a biologist - and she said that we each have a dominant and recessive rh factor --- so if you have a parent of each, the + will dominate, but you will carry both. She told me that both her and my dad are positive, which makes me a ++, therefore, no matter what my husband is, our baby is +. It takes a lot of worry off my mind!
