Any Nurses out there expecting a May baby?

Cathy
How many nurses or shift workers are about?
I'm a RN working in a private hospital in Australia. I'm currently sitting in my car, willing myself to head in for night duty. Man I am tired, I have slept even less than usual and can't take anything to help. I think this is going to be a difficult journey. I work in physical rehabilitation/medical and wondering how I will keep this pregnancy a secret if I have an infectious patient. 
I would love you hear your stories! Let's go through this together!
