Sovereign Immunity, please?

Being pregnant seriously compromises the immune system, which I think is a bit of an oxymoron in the grand scheme of things, especially the notion that the body does whatever it is supposed to do to transform itself into a baby making machine. Why does that not include an immune system boost?

Apparently, my body's immune system has been weakened, ironically, by myself (my brain?), in order to prevent myself (or my body?) from expelling the fetus, which I guess does live a sort of parasitic existence within my womb. But if the sole purpose of the womb (uterus) is to bear children, then why should the entire body be at odds with that function? And is the immune system some sort of small child that is controlled by the brain, competing with the uterus for attention? At least, that's what it seems like. I am too non-versed in medical terminology, or basic physiology for that matter to understand the functions of the body and what gets precedence over what. So I will continue my bitching session without guilt.

Here's another interesting loop in the chain of command. Because (or maybe not because, just in lieu of) the weakened immune system, the uterus, whose primary purpose is to protect and nourish the fetus, apparently sufficiently protects the fetus from any viral infection such as a cold or flu that may ravage the mother. But in my internet food/pregnancy expedition yesterday, where I was trying to find something that would make me feel ok about eating the brie and salami I purchased a few days ago, as well as all that cut and peeled honeydew melon and pineapple that is just screaming "eat me" from the refrigerator, I found out that the food poisoning agent listeria does pass through the shield of the womb, through to the baby, and can either kill the baby within the womb, or cause a serious infection leading to death once the baby is born.

What's wrong with the body? I don't get it. Perhaps it's just a cruel function of evolution that will one day resolve itself.

So anyway, I'm sick. And I'm trying not to sneeze and cough for fear that I will agitate the subchorionic hemmorage - the hemmorage which I don't even know is there or not anymore. This sucks ass.
