Hi all. I'm 19 weeks pregnant and work as a float nurse on telemetry units. Recently I have become so paranoid about being exposed to sick patients at work that I have a fear of acquiring birth defects from exposure to random things. As a nurse I already know what I can and cannot be around in the hospital setting, but again I'm paranoid because I feel like sometimes patients aren't diagnosed right away or sometimes you may not even know what they have. I need some reassurance because it's starting to cause too much stress on me. Thanks for any words of advice
