Blood type sciency stuff.

I found out that my blood type is O negative a few months ago. The universal donor. Should I add that I have never donated blood (yet)?  I was always bordering on the accepted weight before, and then in England we could not donate because BFG was an  "African male" and I had slept with an "African male". I plan to start donating when I am not pregnant though, my blood is useful!

All this blood type stuff is not important to the majority of the population when you are pregnant, unless you have the "negative" part attached to your type. Then things get a bit complicated. Yippee.

People who are RH - do not produce the RH antigen, so if we are given RH+ blood with the RH antigen our blood forms antibodies against it and  kind of attacks it. So if you are a negative mom and you have a positive baby and your blood mixes at any point during or after pregnancy, mom's blood will then attack any future positive babies you might have if any mixing occurs again. Yikes.

This RH negative blood type is rare. Of course it is. Of course I am left handed, RH negative, and apparently have a personality type that is very rare for women. Only about 15% of white people have the negative type, and only about 5% of black people! I should just add that there are some VERY rare blood types and clotting issues and other mutations that it seems I do not have, so I am very lucky. This RH stuff is not a very big deal. Just an expensive deal. The injections they give you to block your response against RH positive blood cost R700 each time and they give you at least 3. More if you have any kind of injury or bleeding during pregnancy. And I do not have the kind of medical aid that covers that stuff so we would be paying it all.

Luckily for me I managed to hook another rare RH negative person in this RH plus sea. BFG is RH negative too! This means we have no chance of producing a positive child. And negative blood does not attack other negative blood. How awesome is that? And how slim the chances. No injections for me! Shew, this pregnancy was already costing more than it should have. I just feel a bit sorry for our kid. Being negative just seems to be more trouble than it is worth.

It seems the BFG really is perfect for me in every way :D
