BW, sorry to hear that you are going through a bit of tough time ATM...I agree with the girls already said, you are absolutely in the right to follow up with the school, even they don't give the name, they should be able to tell you if you are exposed to it.

As of too late to contact them and OB, maybe google can get you through tonight? I know how worried and angonizing it could be....I acutally just did a quick search (I can PM you if you need the link), it seems that it is not that contigous like other infection and they said basically the effect to an unborn child is none...

On a brighter side, I just saw your ticker, wow, almost 20 weeks, that's half of the pregnancy, well done you for making it this far. I am sure this is just a little hurdle you need to get through and will get through
