colds and pregnancy don't mix

Well thanks to these boarding school kids and all of their germs, i'm now laying on the couch for the second day feeling like garbage! It's just a silly cold so I wasn't sure why I was feeling this crappy - then i looked up some things online and read how pregnancy decreases your immune system so that your body doesn't attack the foreign object in the body (that would be the baby) which makes pregnant women more susceptible to illness. So now it makes more sense to me why a little cold is kicking my butt, but it still stinks! Now the question is, do I just suck it up and go to work, meetings, and dorm duty, or is it something I have to take more caution with than I normally would? Questions, questions....
