Since I have gotten pregnant I have learned a lot of interesting things about reproduction. Like for instance did you know that anywhere from 10-25% of all clinically recognized pregnancies will end in miscarriage?
I have also learned about the Rh factor and how incompatibility with blood types many times makes it hard to conceive. Here is information below...
What causes Rh disease?
An Rh-negative mother and an Rh-positive father may conceive an Rh-positive baby. When this occurs, some of the fetus’s Rh-positive red blood cells may get into the mother’s bloodstream during pregnancy, labor and birth. Because red blood cells containing the Rh factor are foreign to the mother’s system, her body tries to fight them off by producing antibodies against them. This is called sensitization.
Once a woman becomes sensitized, her Rh antibodies can cross the placenta and destroy some of the red blood cells of an Rh-positive fetus. In a first pregnancy with an Rh-positive baby, there usually are no serious problems because the baby often is born before the mother is sensitized, or at least before the mother produces many Rh antibodies. However, a sensitized woman continues to produce Rh antibodies throughout her life. This means that in a second or later pregnancy, an Rh-positive baby is at risk for more severe Rh disease.
I never knew that reproduction was so complicated. Its kind of mind blowing! I just thought I'd share my new found information with others... I find this all very fascinating and I am looking forward to learning more things. I also find it very ironic that I got knocked up when I took my husbands virginity... and we have conflicting blood types. I don't know if I'm positive for the antibodies yet but damn... the stats of me getting pregnant were really low. And its even more mind numbing that I'm in my third trimester now and still healthy!
