What, the Chickenpox?!

Today my principal stopped me to let me know that one of my students has the chickenpox. Normally this wouldn't concern me because I had the chickenpox as a child, right? Well, I just don't know. I'm almost certain that I had the chickenpox when I was little, but my mother has no memory of this blessed event in my life. Ok, now it's time to worry. I called my doctor (I had called before when I thought I had had it and no problems) to let her know that as it turns out, it doesn't look as though I've ever had the chickenpox. Her response, "Oh, that's not good." So off I went to the lab again to have more blood drawn to see if I had chickenpox. While that is all well and good, the bad news is if I do have chickenpox there's NOTHING we can do. I just have to suffer through it and hope the baby isn't affected. I was told that the greatest risk to her would have been within the first 20 weeks of pregnancy, or if I were closer to delivery. She should be protected in the womb, but there's still a risk. Just what I want to hear.
