Pregnancy Info HOME

that sounds weird. I am O- and if you are neg and your patrner is pos, you have to get a shot to prevent something called IDC where the baby's blood contaminates yours. My Dr said if you get IDC you can never have another baby with a partner who had pos blood. If you do get preg, you will probably m/c or have a baby w/ bad abnormalities. This only applies to neg blood women. Baby gets dad's blood type.

The baby doesn't get the dad's blood type. However, if you are RH negative and the father is RH positive, there is a chance the baby could end up with RH positive blood, which would result in incompatability between the fetus's and the mother's blood. Here's a decent, but short, link that explains it. http://www.todaysparent.com/pregnancybirth/pregnancy/article.jsp?content=20050808_161621_2156&page=1 (Take out any dashes that look like this -)

I am a RH negative mommy and my 1st child was rh positive(they dont know this till after birth). I had to have a shot around 7mths i think and another after labor. I am pregnant again, but had spotting early on so to be safe i got a shot before my 3rd mth and will get another at 7mths and another after birth. This protect the baby and yourself from mixing blood which could cause major problems. But in this day and age it isnt that big of a deal. Rarely do many women have problems due to this in thier pregnancy because science ahs evolved so much. The only way you can get neg blood is by a neg mother, she has a 50/50 chance of having either a pos blood type child or a neg blood type child. The father can not pa__s negative blood on. My mother had negative blood, but my brother and sister did not get it from her, just me :)

baby, where did you hear that the baby doesn't get the dad's blood type? That's interesting. My dr said it does. Now I'm wondering. I have my dad's blood type.

I found some info on rh factors and how they are pa__sed on at http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/rh_factor.html. I see what you mean about how it is now the father who pa__ses it. It must be that my mother also had a neg allele.

I work in blood bank at a hospital and YES the baby does get daddys blood type!!! Very very very very rarely does baby get mommas blood type. I am A- and my DH is O-, so my baby will have O- blood type. The only thing she and I will the same is the RH factor which is -

The baby can get daddy's blood type(o,b,ab ect), but the ph negative factor has to come from a mother not a father.

my brother's GF has rh- and had to get shots when she was pregnant, and as for the blood type thing, i don't know what type my baby's fathers are but my children have my bloodtype o+

Hi, I am O- so where did i get my blood type from and what will happen if im pg. I don't know my husbands blood type.

Just read one of the replys here that said you can only get neg blood from a neg blood type mother. I'm neg blood and my mum is pos. so work that one out!!

Also, my dad is pos as well!!!! No neg parents at all but I am.

the baby can get either parents blood type. also they can be either + or - i am a+ but i have a sister who is ab+ and one who is ab- the mom and dad both give the baby. here is what i found on the net: each biological parent donates one of their two Rh alleles to their child. A mother who is Rh- can only pa__s an Rh- allele to her son or daughter. A father who is Rh+ could pa__s either an Rh+ or Rh- allele to his son or daughter. This couple could have Rh+ children (Rh- from mother and Rh+ from father) or Rh- children (Rh- from mother and Rh- from father). Mother Father Child Rh- Rh+ Rh+ Rh- Rh- Rh- . A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies. Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. A blood test of either type AB or type O is more informative. Someone with blood type AB must have both the A and B alleles. The genotype must be AB. Someone with blood type O has neither the A nor the B allele. The genotype must be OO. Each of us has two ABO blood type alleles, because we each inherit one blood type allele from our biological mother and one from our biological father. A description of the pair of alleles in our DNA is called the genotype.

The problems occur when the babies blood group is different to yours and it is usually only when the mother is Rh-. The + in blood groups is the dominate factor so if you are negative (which you aren't) there is cause for concern. Usually during your frist pregnancy you are fine but you may be given Anti -D if there is any bleeding or you have a bad accident/fall just in case. I am rh- and get anti-d at 28weeks, 34weeks and after the births of all my children since they were all positive. There is no blood group that means you can't have children and even if there is a problem with the blood group mixing whilst pregnant it doesn't mean you can't have future pregnancies. You will just be checked more often.
