Hi Shannon, I remember a bit about this from nursing school and dug out one of my old books to make sure I remembered correctly. No it will have no effect on conception. Your OB doc should do a blood test to check your RH factor at your intial prenatal visit. There are is a medicine that your physician will use if its found that you are RH negative and the baby is RH positive in order to minimize any risk to your baby. You are not at risk of any harm yourself. I hope that helps. If you have concerns about RH factor please also talk with your physician.

The Rh factor does not affect if you can get pregnant but it does affect your pregnancy afterwards. It has to do with the antibodies you carry in the blood. My dh's Rh is Positive and mine is Negative (o+ and a-). During pregnancy the baby may have an Rh of positive while I have an Rh of negative. Even though the baby has a separate blood system, blood from the baby can cross the placenta into my system. A small percentage of pregnant women with Rh Negative blood who carry an Rh Positive baby will react to the fetal blood as a foreign substance and become sensitized by making antibodies. These antibodies then go back to the baby and attack the fetal blood, breaking down the red blood cells and producing anemia. The condition is called hemolytic disease. It can become severe enough to cause serious illness, brain damage, or even death in the baby. Once formed, these antibodies do not disappear.
All Pregnant women should have a blood test done at an early state of pregnancy.
Definitely get more information about it from your Doctor. The above information was given to me by my doctor on my condition. I believe that an injection of Rh Immunoglobulin helps to prevent the bad stuff from happening.

I haven't ever heard of it affecting conception.
