My parents have opposite blood -/+ A type. If I remember my Mom told me that when she was pregnant with us (4 kids) that our blood that was positive , fought her blood that was negative. She had to be monitored, but all of us turned out fine. This was over 30 years ago.

Rh incompatibility usually isn't a problem if it's the mother's first pregnancy because, unless there's some sort of abnormality, the fetus's blood does not normally enter the mother's circulatory system during the course of the pregnancy.

Rh antibodies are harmless until the mother's second or later pregnancies. If she is ever carrying another Rh-positive child, her Rh antibodies will recognize the Rh proteins on the surface of the baby's blood cells as foreign, and pass into the baby's bloodstream and attack those cells. This can lead to swelling and rupture of the baby's red blood cells. A baby's blood count can get dangerously low when this condition, known as hemolytic or Rh disease of the newborn, occurs.

Today, when a woman with the potential to develop Rh incompatibility is pregnant, doctors administer a series of two Rh immune-globulin shots during her first pregnancy. The first shot is given around the 28th week of pregnancy and the second within 72 hours after giving birth. Rh immune-globulin acts like a vaccine, preventing the mother's body from producing any potentially dangerous Rh antibodies that can cause serious complications in the newborn or complicate any future pregnancies.

A dose of Rh immune-globulin may also be given if a woman has a miscarriage, an amniocentesis, or any bleeding during pregnancy.

If you're not sure what your Rh factor is and think you're pregnant, it's important to start regular prenatal care as soon as possible - including blood-type testing. With early detection and treatment of Rh incompatibility, you can focus on more important things - like welcoming a new, healthy baby into your household.

During pregnancy, Rh-negative is the only one of these blood groups that can cause a problem. It turns out that an Rh-negative mother can make antibodies (part of her immune system's response to invaders) against Rh-positive blood cells, even against those of her own baby. This is called Rh sensitization. These antibodies have the potential to cross the placenta and attack the fetus' red blood cells, which in turn can cause low blood count (anemia), congestive heart failure, and even fetal death. This is called hemolytic disease.

Fortunately, nowadays, there is such a thing as Rh sensitization is preventable with a medicine called Rh immunoglobulin (RhIg, or Rhogam™.) Since an Rh-negative mother will develop antibodies against Rh-positive blood cells (become sensitized) only if fetal blood crosses the placenta and enters her bloodstream. The injection of Rh immunoglobulin blocks the mother's immune system from seeing the fetal cells, if they do happen to get into her bloodstream, so she will not become sensitized and make antibodies.

Rhogam is given at times during the pregnancy when there is some likelihood of Rh-positive fetal blood getting into the mother's bloodstream. This includes

Amniocentesis

Miscarriage or ectopic pregnancy

Elective termination of pregnancy

Around 26 weeks of pregnancy (which protects through late pregnancy)

After delivery

The baby's blood type is checked at birth, using blood obtained from the umbilical cord. If the baby turns out to be Rh-negative as well, the dose of RhIG usually given at delivery is not necessary.

You let your doctor know when you get pregnant. There is a shot that they will give you I believe after you give birth to make sure that you don't have any RH factor problems with your next baby.

Years ago some birth defects could be attributed to an Rh neg mother giving birth to an Rh positive baby (1st) then having a second baby...but this was 40+ years ago. It happened to my little brother...and wasn't discovered until I got pregnant and found out my blood type. His birth defect was dealt with quickly with surgery and had no lasting effect on his health at all.

Just talk to your doctor. It will work out fine!!

The woman is rh negative. If the baby has a positive blood type and the blood mixes in the cord, the womans body will attack teh baby. You need to get rhogam shots to give your body poistive antibodies so this won't happen. You get the shot twice in the pregnancy, and if there is any bleeding during the pregnancy you need to get a shot. They test the baby's blood when its born. If it has rh positive blood you get another shot of rhogam.

Well, if you have neg and he has positive it is very very very important that you tell your OB asap. It is not dangerous yet, but it would be for you next pregnancy. All you will need is a Rho gram shot at about 28 weeks. It is not a biggie. But, if you are planning on having more children, it is gravely important that you tell your OB... They will just write it down and you will be ok... Congrats and Good Luck. You are very smart to notice this problem.
