It's not the O factor that they are worried about it's the rh factor which is negative. If the father of your child is positive then your body can reject the pregnancy and attack the fetus if the baby would have the positive rh factor. I am a negative and I have had to under go one shot one time and two shots another time due to conflicting rh factors. It's nothing that the doctors can take care of. This is more common than not. Take care and have a good pregnancy!

This is what I was referring to with the second baby. For some reason, your body will not attack the baby on your first pregnancy unless the babies blood gets into your system. Any subsequent pregnancies it will automatically attack a + rh factor baby.

I am O- and my husband AB+. The others here are right about the RH factor and that a second baby could be more at risk if you are not treated with Rogahm shots during pregnancy. I got my first shot at 20 something weeks and another immediately following the birth of my first child. During the second pregnancy I again got a shot at 20 something and again immediately following the birth of that child. Each time as part of prenatal care I was also tested for the RH antibodies and also got a wallet card to carry with me for medical info in the event I was ever found unconscious while pregnant so doctors would know to carefully monitor any fetus and if I were to give birth while unconscious they would treat me with Rogahm to maintain the protection from RH antibodies. My daughter, first child, had a blood problem and had to be under the Bili lights for several days. Her problems might have been related to an RH problem as the estimation of my conception was off by about a month so I might not have gotten the shot soon enough. Even though I tested negative for RH antibodies I might have had a small number that crossed the placenta. Being worried about the RH factor I asked about her blood type right away. All they could tell me for sure on the first day that it was red and human.. :-) Her blood was so messed up they tried for three days before they could even tell me it was in the B group then after another 3 days could tell me for sure it was B+. She got to come home for a day and was ordered back in the hospital as they finally had culture results confirming she had a blood infection. A week of antibiotic shots three times a day... I cried each time they had to stick her but all was well after a week. If you are scared of or hate needles just think about having to watch them stick your child and you won't mind the needles so much.

Take it easy. My mom has this blood type but it didn't have a bad effect on me. Everything will be alright and you will have a healthy baby. I love China

Congrats on your pregnancy, questionsnoanswers. Is this your first pregnancy? I am also O negative. There is only a concern if the father has a positive rh factor blood, because you could produce a postive rh factor baby. There are sometimes cases when a babies blood could get into the mothers system and if your baby is positive your body will form antibodies to treat the baby like an intruder. The shots they give you will stop your body from producing these antibodies. I believe you get the shots at around 28 weeks, and then may again at birth. It really is a common thing they doctors deal with regularly and you should not be concerned too much. I don't understand this part completely but there is more of a concern with the second baby. You just want to always make sure your doctors know you are O negative. I hope you have a good pregnancy.

The "o" is nothing to worry about the the rh factor, which is you being a "-" is something your doctor should be concerned about. There are shots they will give you to make it ok. There is also alot of information out there about it. Are you recieving regular medical care? Well, anyway, it should be fine if you are cause the docs will know just what to do about it and everything should be good. Congradulations on your pregnancy! Try to document everything cause pregnancy and children have a way of erasing your memories! Do you know what you are having? Any names picked out yet?
