I just misscarried my baby because of my blood type O negative.?

Question

Does anyone have any more information on why this happens. Or any research that has been done on it.
Is it common.

Answer 1

In addition to the blood group (A, B, O, AB), the Rh factor is written as either positive (present) or negative (absent). Most people are Rh positive. This factor does not effect your health except during pregnancy.

A woman is at risk when she has a negative Rh factor and her partner has a positive Rh factor. This combination can produce a child who is Rh positive. While the mother's and baby's blood systems are separate there are times when the blood from the baby can enter into the mother's system. This can cause the mother to create antibodies against the Rh factor, thus treating an Rh positive baby like an intruder in her body.

If this happens the mother is said to be sensitized.
A sensitized mother's body will make antibodies. These antibodies will then attack an Rh positive baby's blood, causing it to breaking down the red blood cells of the baby and anemia will develop. In severe cases this hemolytic disease can cause illness, brain damage and even death.

Answer 2

I also have the O negative blood type. I misscarried my first pregnancy. Since then, I have given birth to three healthy little girls. Each pregnancy went well, the babies were healthy. i don't know why I misscarried. I don't know if it even has anything to do with the blood type. I do know that most likely you won't misscarry all of your pregnancies. I just had one bad exerpience with pregnancy, and it happened to be my first. Don't let the misscarriage get you down. I know it's easier said then done, I've been in your shoes. There is hope. Give your body some time to heal, then maybe try again. It is possible that you may need a Rhogam shot. I have them with each pregnancy and also with each delivery. The shot isn't that bad. They'll draw some blood and do some blood work, then give you a shot. It's not as bad as it sounds. I'm sorry to hear about your loss, and good luck.

You may have a condition that allows your body to form blood clots. It's rare but on the rise. Sorry....I forget the name. But a red flag to it is consistent miscarriages. ( you didn't mention if this your first miscarriage ). The only two words I can think of associated w/ it is d-dymer (a blood test) and lupus (not the common one). Also, there are four major blood types with an rh factor. O,A,B, AB. Think of it as this way: O is just plain milk chocolate, A is milk chocolate w/ nuts, B is milk chocolate w/ nuts and coconut and AB is milk chocolate w/ nuts, coconut and raisins. If you melt O and mix it w/ B, does B change? No. You're not adding anything new to B. But if you melt B and mix it w/ O, have you altered O? Yes. Because you've just added nuts and coconut to just plain milk chocolate. The rh factor, think of as mint. So, if you are O-, you don't have any nuts, coconuts or raisins or a mint. So, your blood can not ever, EVER accept anything else except O-. If you do, you'll clot and die. But if your blood was AB+, you have everything: chocolate, nuts, coconut, raisins and a mint. You can accept any and every blood type because there is nothing that the other blood types have that you don't already have. This is the 'science' behind blood typing.
I went on too long. I hope you're pregnant and that you have a beautiful, happy, healthy baby. Merry Christmas.

Not really sure if the cause is truly your blood type. If it is...they need to make sure you had the RH- Shot after your miscarriage expelled from your body...this will keep you from rejecting all other pregnancies. I am A-, and had some slight bleeding, so they went ahead and gave me the shot...it is not to help this baby...bc my body is not going to reject him now...but it could affect future babies...as my body will see it as a intruder and get rid of it. I will have another at 28 weeks, and then after deliver.

Dont think you rejected this child bc of your bloodtype. I would aks the doctor again...maybe he was just guessing. Miscarriages eerly can be anything...maybe something wrong with baby, so nature decided to do its thing.

If you have had a miscarriage before and they did not give you a shot...then yes...you could have misscarried bc of this!!

I am sorry for your loss!!!

Answer 5

I know that when a person is O negative.. then this is the only blood that they can recieve.. opposed to if you were a Positive blood type because of the RH blood factors. After you deliver the baby.. the mother always gets a shot of Rhogam I beleive because of the negative blood type and after the miscarriage you probably got this shot. The only thing I can think of is if the babies blood somehow crossed into yours. Your body would of rejected it if the babies blood type was positive.

Answer 6

Make sure you get a shot. When you're RH - anytime you miscarry, give birth or bleed during pregnancy you have to get a shot within 72 hours!

I'm just guessing, but you may have had a chemical pregnancy or something in the past where the baby's blood mixed with yours and you didn't get a shot. If so, that would cause anti-bodies to form and they could attack the embryo during the next pregnancy. Ask your Dr. for more info, it's quite possible that your miscarriage had nothing to do with your blood type.

You really need that shot or you could have problems with subsequent pregnancies. Good luck!

Answer 7

Negative blood types see a pregnancy as an infection or invasion of the body and try to fight it off, that is why they give you the riogram shot to sustain the pregnancy, also miscariiges are more common than you think, some women have them when they think it is there period, If you are going to try again make sure you visit with your doctor first and he can let you know the steps to take to keep a pregnacy.

Answer 8

The only reason your blood type would be the reason is if you are negative, your baby is positive, and your body tried to kill the baby. It would only do this if antibodies were built up. That could only happen if you've carried a previous positive baby (delivered, miscarried, aborted) and didn't get the rh shot. Are you sure that is the reason?

I'm so sorry for your loss.

A mother's negative Rhesus factor can cause complications when the fetus has a positive Rhesus factor. However, many many women with negative blood types go on to have babies who are perfectly fine. Talk to your gynocologist. Make sure you get the rhogam shot.

Below is a little info about Rhesus factors and maternal antibodies.

Answer 10

Have you received a shot of Rhogam yet????? If not, you need to.

I don't know for sure, but i think there are additional reasons to why you miscarried. Just having type o negative blood is not the reason, unless you have previously given birth, miscarried, or had an abortion and never received your rhogam shot. You need to get it WHILEyou are pregnant and after. Doctors give the shot to you regardless of what your baby's blood type is. If you are negative, you get the shot. So, to protect yourself next time, go get it!!

You should talk to your doctor about your history and about getting Rhogam. Your blood type is not the only factor.
